Statistics in Health... Is There a Connection Between School and Workplace Statistics?


Research to determine the use of statistics in health carried out by health professionals in their workplace was carried out, concerning statistical techniques, research methods by a survey in 2019. This article reports three main findings. So far, (i) describes the needs and the opinions of the health professionals, (ii) goes to the training programs and identifies if the needs are covered by the training programs, and (iii) implements corrective measures to overcome the need not covered by the training programs. The research identified gaps between subjects and methods taught at university and the ones used in the workplace by health professionals. In the health professionals’ opinion there is inadequate statistics education for alumni during their studies. Based in their opinion, researchers identified some changes to courses programs which should be implemented.


Statistics education; Statistics in the workplace; Health professionals; Curriculum development; Workplace needs


According to Ocaña-Riola et al. [1] the bases of statistical inference and contemporary statistics were set in the early 20th century. Straightaway, these statistical methods were used in health research but almost immediately Fisher [2] warned that mistakes were being made. Furthermore, during the second half of the 20th century, there was a remarkable surge in scientific evidence alerting to the errors that many researchers were making in applying basic statistical methods [and that] this issue became so serious that Douglas Altman, Director of the Centre for Statistics in Medicine in Oxford, qualified inappropriate use of statistical techniques in biomedical research as a scandal, in one of the most striking articles for the scientific community published in the 1990s. Given that many medical decisions, including disease diagnosis and choice of appropriate treatment, were based on statistical tests, this situation took on a very serious note.

Ocaña-Riola [1] says that the reason for the mistakes made by researchers and health professionals who use statistical methods is the lack of training and knowledge in the field of mathematics (which includes the area of statistics), and as a result, the findings only contribute further to spreading false conclusions. The statistical community and the spread of information about the lack of statistical knowledge which caused poor decision-making led to question whether the mathematical content embedded in working practices is widely understood or achieved by a small number of experts. To quote a National Research Council workshop report,

Mathematics in the workplace is quite different from mathematics in school. It is more concrete and more intuitive, yet at the same time more exacting and more unpredictable. It is rich in data and inextricably linked with technology. Technicians and other workers are routinely expected to carry out multistep applications of simple mathematics--especially three-dimensional geometry, triangle trigonometry, and elementary data analysis [3].

Statistics education is a necessary element of health professionals’ education. Given the need to ensure professional practice based on evidence, they need to know how to interpret statistical information, especially in scientific studies of healthrelated specialties, in order to better exercise their profession. In this sense, they must be statistically literate to be able to interpret the data resulting from research and practice and conveyed in meetings and scientific articles. Thus, being statistically literate is a minimum requirement, for health professionals to develop their statistical reasoning. As decision-makers, health professionals must develop some knowledge in statistics [4], which includes one or more of the following skills: literacy, reasoning, and thinking.

Firstly, health professionals should develop sound statistical knowledge to be informed consumers. Like any other tool, statistics can be used or misused. It is true that some individuals do actively lie and mislead the public with statistics. More often, however, wellmeaning individuals unintentionally report erroneous statistical conclusions. It is fundamental that everyone, and, in particular, health professionals, knows some of the basic statistical concepts, in order to be in a better position to evaluate the information that is given.

Secondly, health professionals need to be able to read and understand articles in scientific journals. Almost all technical journal articles contain some form of statistics. When readers are deprived of an understanding of statistics, the information contained in scientific articles will be worthless and can be wrongly comprehended.

From Brown’s [4] point of view, an understanding of basic statistics will provide health professionals the fundamental skills necessary to read, understand, and evaluate most results. Furthermore, the ability to understand, interpret and critically evaluate research from a statistical perspective are fundamental skills that facilitate understanding throughout coursework in their formative path.

Thirdly, health professionals must be able to effectively conduct research. They must know what statistics they need to use before they collect data, since, otherwise, the data collected might be uninterpretable. Unfortunately, when this happens it results in a loss of data, time, and money. Even during their training, conducting research is a requirement (for instance, designing and conducting a final research project).

Finally, statistical knowledge further develops critical and analytic thinking skills. Although, most students completing high school and introductory undergraduate course works have at their disposal a variety of critical thinking and analytic skills, the study of statistics will serve to enhance and further develop these skills. To do well in statistics one must develop and use formal logical thinking abilities that are both high level and creative.

In Portugal, statistical knowledge has become a leverage for the career of health professionals. On one hand, health professionals are demanded to interpret statistical data and draw conclusions based on statistical information; on the other hand, they are required to engage in statistical investigations, which include data collection, processing, and analysis. In particular, being statistical literate assists health professionals in decision-making processes and works as an important tool to conduct research and correctly interpret evidence-based readings.

Most Portuguese graduate programs in Health Sciences require one or more courses in statistics in order to prepare students to engage in statistical investigations and make sense of data. This does not mean that all health professionals will engage in statistical research in their profession, but rather that they have the means and tools to do it, in case it becomes necessary. Those statistics courses have a dual focus. On one hand, they focus on the mathematical theory of statistics, which is typically not contextualized in realworld situations. On the other hand, they focus on how to use statistics (e.g., how to design an experimental study, how to select a proper statistical method, or how to interpret statistical reports in a scientific paper). The Bologna reorganization of higher education offered the opportunity to emphasize the practical aspects of statistics and contextualize the learning of statistics in real-world situations, engaging students in solving problems involving realworld, complex data. Yet, statistics courses in most graduate Health Sciences programs still separate theory from practice, in such a way that students feel there is no usefulness in understanding the mathematical theory behind the statistical procedures they learn to master.

In the first author’s experience as a teacher and as a statistical consultant, the statistics education that health professionals encounter in their formative path, in higher education institutions, has a rather theoretical character, and much of what they learn is hardly ever used at the workplace. This is not so regarding descriptive statistics, but considering factual experience and health professionals’ opinions, it is true concerning inferential statistics. Thus, health professionals must develop a significant autonomy in searching the statistical methods that better suit the complex situations they encounter at the workplace. Health professionals do have to become competent in designing and conducting scientific research, involving statistical notions and making sense of data, as well as in developing an investigative, reflective, and critical stance towards data and statistical information. Therefore, they have to move beyond being statistical literate to developing their statistical reasoning. In brief, being statistical literate is necessary for all citizens and primordial to health professionals, even those who do not carry out research, because if they want to fulfill their professional tasks with quality, being able to interpret and understand statistical data about, for instance, drugs, diseases, etc., is a basic requirement. Statistical reasoning involves an explicit process where facts are identified, relationships are established, and inferences are made.

The Bologna agreement recommends the creation of a learning environment that favors classroom interaction and student participation in class discussions, moving away from direct teaching approaches. Yet, in our view, the document has had a practical expression lined much more to reorganization and restructuring than to changes in learning environments and teaching approaches. There have been more modules in the course structure, but this means more segmented content matrices, with no significant changes in the general content matrix and leading to compartmentalization instead of integration. Class size has diminished, but typical approaches are based on lectures, focusing on subject-matter, not on real-world problem situations, which should be tackled and discussed collectively, from a critical stance. Thus, the focus is essentially subject-based, rather than problembased, that is, the emphasis is on learning theoretical statistical notions, instead of being on problem-solving processes using statistics.

Subject-based approaches are efficient and required. Nonetheless, the heavy focus on course program/content may harm further learning by leaving students with the impression that they have learned all that is worth knowing about statistics. Furthermore, if the statistical concepts are not incorporated in their knowledge and future problem practice, it may be difficult for professionals to recall and apply these concepts later, in the workplace. On the contrary, courses taught using problem-based learning methods give health sciences graduate students direct practice with the statistical reasoning skills needed to choose appropriate procedures for analyzing data from their research studies and give them a sense of purpose in their learning of statistics. Considering the current need to make decisions based on evidence, it seems to be urgent to make real the promise left by the Bologna agreement.

Medical science is, in its nature, inseparable from an understanding of probability to interpret data and therefore to draw valid conclusions. Even so, most doctors know little about statistics, struggling with it even in their own specialty [5,6]. Research has documented difficulties in understanding probability and in reasoning about chance events [7,8] distributions, and graphical representations of distributions [9], which are basic notions underlying core statistical concepts. Such difficulties necessarily lead to obstacles in learning statistics. In fact, studies have pointed out that both health professionals and students frequently misunderstand health statistics themselves.

Attitudes of health professionals and students towards statistics are often unfavorable [10-15]. Attitude can be defined as a disposition to act in a certain manner in precedence to others, depending on the experience one has of the situation about to face [16]. There is a crescent number of studies suggesting the existence of positive attitudes among health professionals and students towards statistics, along with a clear recognition of its importance [17]. Many, however, still experience anxiety and consequently show negative attitudes towards statistics. In fact, several practitioners and students in health sciences training, including in medical schools, frequently find statistics courses far too challenging, probably because of their perceptions of the subject’s difficulty and their lack of a solid background in mathematics [18]. In multiple domains, attitudes towards statistics are positively correlated with statistical knowledge [19]. These attitudes are also related to attitudes regarding scientific research as a whole [20]. However, during a statistics course, positive attitudes have been shown to improve over time, alongside with students’ proficiency [21].

This study is drawn from the implications of the first author’s experience as a teacher and as a statistical consultant involving health professionals. Based on the first author’s experience as a statistics teacher in higher education institutions, in the health sciences area, there seems to be a lack of adequacy of statistics courses in health sciences programs, in terms of preparing health professionals to exercise their profession appropriately equipped with statistical knowledge. In some cases, there seems to be even a complete absence of statistics preparation of health professionals in order to become competent in their future professional practice. Based on the demand for statistical treatment based on the demand for statistical data treatment by health professionals, either during the year of specialty, or when the theses dissertation, or just for data treatment for congresses and publications, the demand for statistical treatment is very high, just look at the number of companies that provide statistical consultancy services and their demand. ASA [22], states that “Statistician is listed among the Bureau of Labor Statistics’ fastest growing careers in 2018 and it’s predicted to grow 33 percent by 2026”.

Research goal and questions

In this article, we examine the relationships between the statistical education of health professionals and the statistics used in the workplace, from the perspective of those professionals. Our study was guided by the following research questions:

1) How do health professionals perceive the contents and methodologies used in the statistics courses taken throughout their formative path?
2) How do health professionals assess their own statistical knowledge at the end of their graduate program?
3) What statistical notions and methods do health professionals use in their workplace?
4) How do health professionals associate the statistics used in the workplace with the statistics learned in their graduate program?


Statistical Literacy, Reasoning, and Thinking

Statistics has a very important role in people’s lives, even though sometimes they don’t recognize it. As a matter of fact, with its ideas and methods, statistics allows the understanding of several aspects of today’s society and facilitates decision-making in a world characterized by uncertainty and variability [23,24]. So, as schools and universities should prepare students for their future, it is fundamental that they promote and develop statistical knowledge [4]. But what is statistical knowledge? Several researchers have distinguished the following notions: statistical literacy, statistical reasoning, and statistical thinking. Yet, according to Ben-Zvi and Garfield [24], there are no consistent definitions of those concepts.

With regard to statistical literacy, these authors state that it includes basic and important skills that may be used in understanding statistical information or research results, such as being able to organize data, construct and display tables, work with different representations of data, an understanding of concepts, vocabulary, and symbols, and “probability as a measure of uncertainty [8]. According to Iddo [25], statistical literacy concerns a person’s ability to be an effective data consumer, e.g., to interpret, critically evaluate, and communicate about statistical information and messages. In a similar approach, Mendonça and Soares [26] perceive statistical literacy as the ability to argue using statistical terminology, in addition to important skills that can be used in the understanding of statistical information. This competence is also associated with the ability to interpret statistics in articles, news, and other sources of information.

With regard to statistical reasoning, Ben-Zvi [8] define and place it on a higher level than statistical literacy, considering that statistical reasoning “means understanding and being able to explain statistical processes and being able to fully interpret statistical results” Iddo Gal [25], for his part, argues that it involves mathematical reasoning and making sense of statistical knowledge. In particular, it involves a mixture of ideas about data and chance. Garfield [27] defines statistical reasoning “as the way people reason with statistical ideas and make sense of statistical information, [which] involves making interpretations based on sets of data, graphical representations, and statistical summaries”. A physician faced with a new finding in his field, a pharmacologist analyzing a series of experiments, or a nurse assessing the scientific aspect of the new technique must understand statistical aspects and activate their statistical reasoning.

At a higher and more comprehensive level, there is statistical thinking that encompasses both statistical literacy and statistical reasoning as it “involves an understanding of why and how statistical investigations are conducted and the ‘big ideas’ that underlie statistical investigations” [8]. In addition, according to Iddo Gal [25], statistical thinking is the ability to transform a real-world problem into a statistical problem and to know which method, measure, design, or model applies to this particular problem. So, although these three cognitive processes may be involved in any statistical content, it is possible to distinguish them by analyzing the nature of the task itself. Therefore, to develop statistical literacy, students should be asked to identify some statistical concepts, describe graphs or interpret a result obtained from a statistical procedure. If the purpose is to foster statistical reasoning, students should be encouraged to explain why or how certain statistical results were produced and justify a result or the choice of a representation. Finally, if the purpose is to develop statistical thinking, students should be defied to apply, criticize and assess the conclusions of a study or to generalize the statistical knowledge obtained [8,28]. Ben-Zvi [8] evoke that there are common aspects among statistical literacy, reasoning, and thinking, but they argue that there is a hierarchy among the three competencies mentioned above. Figure 1 depicts such hierarchy.

Garfield [29] as well as [30] discuss the development of these three interrelated statistical competencies: from statistical literacy to statistical reasoning and statistical thinking, based on the interpretation and critical understanding of information derived from actual data. They suggest that this progress is based on the interpretation and critical understanding of information derived from actual data and is, therefore, associated with an education aimed at the formation of a citizen who critically lives in a society. Snee [22] also argues that by letting students play a more active role in learning statistics and by establishing a greater connection with real-life data and problems, students give greater meaning to statistical tools and concepts, and are closer to experiencing statistical thinking.

Thus, one should work in the classroom with examples that have practical significance for students, where they have to raise problems, formulate hypotheses, collect data, appropriate statistical methods, reflect, discuss and critically analyze the results, considering the limitations with regard to the uncertainty and variability. In sum, the learning of statistics should be based on [29].

According to delMas [31,32], although these three cognitive processes may be involved in any statistical content, it is possible to distinguish them by analyzing the nature of the task itself. Therefore, to develop statistical literacy, students should be asked to identify some statistical concepts, describe graphs or interpret a result obtained from a statistical procedure. If the purpose is to foster statistical reasoning, students should be encouraged to explain why or how certain statistical results were produced and justify a result or the choice of a representation. Finally, if the purpose is to develop statistical thinking, students should be defied to apply, criticize and assess the conclusions of a study or to generalize the statistical knowledge obtained.

Concluding, the main aim of statistics teaching must be not only developing the ability of students to see and read statistical results and data but also to understand and critique them [4].

Statistics Education of Health Professionals

The relevance of statistics in Health Sciences is evident in different ways. For example, when considering the statistics education of health professionals, it can be an important tool to support not only the scientific investigations but also the medical [33,34]. Since their first year at university, health students are expected to deal with various learning materials that contain statistical data. However, the lack of a foundation knowledge and skills in statistics to analyze those materials is likely to lead to a premature negative perception of the subject [35,36]. Thus, it is imperative that this issue is addressed early in the process of training of these professionals, as well as in post-graduate studies, based on the premise that health professionals are not expected to become specialists in statistics, but to be proficient in integrating this knowledge and skills into their everyday practice [37].

In addition, although coursework in medical schools normally comprises biostatistics, which requires a basic knowledge of general statistics, many studies have shown that physicians finish their courses without a strong understanding of statistics [5,6,38- 43]. Moreover, despite being essential to interpret the results of clinical studies [1,13,44,45], some researchers still disregard the need for statistical literacy for judgment and decision making [46].

Finally, Fárdales et al. [32,33] whose study revolves around the main theoretical conceptions supporting the statistical instruction for health students and professionals, defend that the statistical training of the health professional, as a social process, should consider three main aspects. Firstly, statistics training should be asymptotic to the process of training of the medical professionals, consequently responding to its dynamics and to the social requirements of being a doctor, capable of overcoming practice problems. This requires the application of statistical content in various contexts. For example, it is needed: in communication with patients, which involves the explanation of the risk inherent to therapeutics; in the evaluation of the efficacy of a treatment; in the interpretation of the results of diagnostic tests, or simply to understand data in scientific publications. Secondly, statistics training should rely on a methodological approach, since statistics, as a scientific discipline, constitutes a procedural analytical tool that contributes to support the practice of the health professions, emphasizing the role of inquiry, analysis, understanding, assessment, interpretation, and guidance in decision-making. Lastly, statistical education in health should be able to tighten the link between statistics and research processes, as well as between medical practice and social life.

Research has suggested various methods for improving how medical statistics is taught, aiming, on the one hand, to improve performance and, on the other hand, to change opinions that statistics is not important or pointless to practice. However, although some of these recommendations were made some years ago, they are still very updated.

For example, Clayden 1990 suggests the benefits of the collaboration between non‐statistically qualified teachers and medical statisticians, stressing the application of statistical principles to real-and therefore more interesting-medical contexts. Additionally, he states that courses in statistics for health students would be more effective if small group or individualized teaching were used. To help both doctors and statisticians improve the practice of medical statistics, Altman and Bland (1991) propose eight measures: that statistical principles receive greater emphasis in undergraduate medical education; (2) the existence of more post-graduate courses in statistics for doctors; (3) that courses in statistics for medical students and doctors are taught by medical statisticians; (4) the standard improvement of textbooks; (5) that ethics committees pay more attention to statistical aspects; (6) that medical journals observe more carefully the scientific and statistical correctness of the works that they publish; (7) the increase in the number of statisticians in medicine; and (8) the due recognition of the work of medical statisticians by these professionals themselves.

In addition, new teaching strategies of statistics to undergraduate health students have been put to test [36] For example, the use of videos and animations with real-world examples make a difference in the way statistics is seen by students and in how they perform [19]. It is also suggested adopting a practical, applicable, contextual instruction or blended learning over traditional learning [47- 50], as traditional approaches to the learning of statistics do not favor an appropriate development of the ability to reason or think statistically [23].

Concluding, although school and workplaces are both learning environments, they have different activity systems. So, it’s important to consider not only the knowledge of workers but also the codified knowledge of the workplace when teaching [51-64].


The focus of our research was on the statistics learned, needed, and used by health professionals, either confident and experienced practitioners or the novices professionals. We therefore recruited as many subjects as possible. This research is a descriptive study for which we employed the web questionnaire method to gather data at a first moment and, in order to collect more data employed, the on-hand questionnaire method in a second moment. Data was collected in August 2019 through October 2019. This resulted in 434 completed and returned questionnaires.

Data was collected using a questionnaire prepared by the researchers in accordance with the literature. An adapted version of the Course Experience Questionnaire (CEQ) developed by Ramsden et al, 1989, was used.

Although CEQ was available for use at the time of elaboration of the form for the questionnaire, in order to construct a more relevant form suitable for the Portuguese context and that may unambiguously accomplish the purposes of the form, five focus group discussions with graduates of different courses were held to identify the major issues and relevant hypotheses that were considered important by the graduates to quality the adequacy of the contents to their job needs.

The questionnaire was adapted and constructed by the first author and then analyzed by the second author. The differences and possible doubts were discussed. Later the questionnaire was sent by email to a small number of subjects (n=6) filling the career criteria. Participants were instructed to write down suggestions when filling out the instrument. No comments about the instrument were made, and in that sense, no changes of any item were made. It was presumed that all health professionals answered the form truthfully to the best of their aptitude, nonetheless, another round of random health professionals (n=3) outside the previous sample was done to check if they understood the questions properly. On average health professionals took about 6 minutes to complete the form.

The form comprises six sections. The first section consists of an explanation of the study aim. Section 2 collects details of university degrees, major subject and main field of employment. This key descriptive data was requested in order to provide an accurate representation of the sample. The third section of the form comprises only one question to allow the participants to indicate the statistical techniques and methods used at the workplace. Section 3 aimed to establish the frequency of use in the workplace of 46 statistical techniques and eight computer packages and whether these techniques had been taught at university. Section 4 investigated the type of statistical activity in the workplace, the extent to which statistical help was available in the place of employment, and where and when training in statistics and mathematics had been received at university. Section 5 of the form comprises four questions to better understand the participants’ sensitivity to the use of the learned statistics at the workplace, i.e., the adequacy of the school program and year, the impact in the workplace and circumstances where they used statistical knowledge.

The last section asked respondents for any comments they would like to make about the provision of short courses and workshops, the relevance of statistical training for their employment and recommendations for improving university statistics teaching, as well, participants were invited to enter additional comments, any feedback or thoughts on a free-form text area, which might be used for follow-up for clarification if necessary.

Data Collection

Permission for the study was secured from the Universidade do Porto Ethical Committee (UPEC). A condition was that all information would be confidential and recorded by identification number only. The researchers preferred an online questionnaire as they felt it would improve the response rate, nevertheless they went to the institutions and personally they collected many responses. Further, anonymity and confidentiality were assured and maintained.


The target population of our questionnaire comprised health professionals who had in their academic course statistics in higher education curricular program. Professionals were categorized as physician, nurse, and technician. Our sample was constituted by health professionals that were graduated from public Schools of Oporto University. Nonetheless, the target population of the study comprises Portuguese health professionals, the selected sample was composed of the graduates of these three great universities since there will be no major differences with the ones graduated in the rest of the country, as the curricular part of the different courses are similar. We decided for public education, because although there is private education in some of the courses, e.g. nursing, as far as medicine is concerned, there is only public education and therefore we cover all professionals of the same teaching spectrum.


All 434 questionnaires were manually checked for incompleteness and irregularities. All records were entered in a Statistical Package for Social Sciences (SPSS) version 20 for the Macintosh database, and after this procedure, they were checked, and mistakes corrected. SPSS was also used for analysis. Wherever appropriate, Microsoft Excel 2013 was used to modify and create user-friendly charts. The analysis of the quantitative data included descriptive statistics such as frequency and percent. The mean for central tendency and standard deviation for variability were presented.

Demographic Characteristics

Three hundred and forty-three participants were included in the study, of which 87 were males (25%), with a mean age of 41 years (range: 22–61 years) and 256 were females (85%), with a mean age of 35 years (range: 21–58 years). The characteristics of the respondents are listed in Table 1. There was a predominance of nursing professionals (45%), nevertheless this percentage is very similar when compared to health technicians (32%).

Given the years of work experience, we noticed the predominance of professionals who have been in the career for more than 6 years 347 (80%), with the majority having a master’s degree 296 (68%). It should be noted that among professionals who have been working for less than 1 year, 34 (89%) have a master degree and 4 (11%) have a post-graduation degree, while among professionals whose practice is between 2 and 6 years, 42 (86%) have a master degree, 4 (8%) a degree and 3 (6%) have post-graduation degree (Table 2). Among professionals that work for more than 6 years, the mainstream, 220 (63%) have a master’s degree, 82 (24%) a bachelor’s degree and only 3 (1%) have a PhD. We should notice that 3 health professionals that have a postgraduation degree are physicians and that the professionals that have a bachelor’s degree are nurses.

Type of Statistical Activity in The Workplace

Regarding statistical techniques most widely used in the workplace by the 434 health professionals, 378 (87%) states that introductory methods, counting on descriptive statistics, basic tests, and simple linear regression are taught adequately in university, nonetheless, there is a gap, 273 (63%), in teaching both simple and multivariate non-linear and logistic regression, modeling and others multivariate techniques with an emphasis, 395 (91%) of the respondents stating that exploratory and confirmatory factor analysis wasn’t taught or correctly taught in college, in particular. Meta-analysis should also be taught, in 126 (12%) health professionals’ opinion. 93 (74%) professionals also refer there is a gap in exposure of survey design, power analysis, and simulation.

Concerning statistical procedures and activities carried out in the workplace by the 434 health professionals, the most common activity, 308 (71%), comprises data analyses. Follows the importance in understanding analyses in published research, 179 (58%), and only 14 (8%) of the respondents have no need of statistics. To better realize the reactions summary, we defined 3 classes established by the proportions: > 0.40 as frequently used, from 0.10 to 0.40 as moderately used and < 0.10 as rarely used. The techniques that are more frequently used are graphical procedures, basic tests, analysis of variance and simple linear regression. Multiple regression, multivariate analysis of variance, nonlinear and logistic regression, factorial and repeated measures designs, and principal components are said as moderate used. Some of the techniques rarely used are survival analysis, cross-over designs, path analysis, confirmatory factor analysis, Bayesian statistics, adaptive sampling and bioinformatics.

In the last part of the survey, where health professionals were asked about the adequacy of the year in which statistics are taught in their course, all respondents stated that it was not in the right year, and some added that the statistics should be taught later, 174 (40%) stated that it should be taught at the end of the course and 21 (12%) of the health professionals expressed it should be divided in two parts, a first part in the middle of the course and the second one at the end of the course.

Concerning the courses referred as needed to engage their practice needs, 296 proposed topics regarding multivariate methods, 52 courses on advanced regression and generalized linear models, 44 a course on population estimation and survey design, and 19 a course on stochastic processes and time series.


The research showed that in the health professionals’ opinion there is inadequate statistics education for alumni during their 1st, master and PhD studies, and identified for graduates in the health area, some changes to courses programs which should be implemented.


Nevertheless, we pursued the amplest vision of statistics at the workplace, we felt sincerely reserved in what the health professionals might recognize to be statistics activities and other statistical signs in the workplace. We, consequently, cannot decree the risk that we only saw a part, perhaps misleading pool of statistical practces influenced by what they considered interesting and accessible during their studies.

We believe that this study and the proposed changes have advantages and disadvantages: the lack of certainty in the validity of our understanding of each profession has been counterbalanced by the generality of the practices observed. Thus, the emerging discoveries about workplace statistics observed in one workplace could be validated in another new workplace. we believe that this approach is more likely to lead to generalization.


Statistics are useful for analysis and prediction. They can show the scale of a problem, illustrate a given phenomenon, or give other useful information. The ability to focus on things when there is so much white noise. With no statistics, more mistakes would be made.
