Statistical Software:

Use of statistical software is not required for this course and will not be required for any of the examinations. However, I anticipate that many of you will want an introduction to the use of statisitical softwared. Therefore, I will be providing illustrations of the use of Stata version 12. If you are interested in giving this a try (and, again - this is optional!), you may purchase it at discount by following the instructions on the pp 2-4 of the pdf of this syllabus

Course Description

This course is the first of a two semester sequence: PubHlth 540 - Introductory Biostatistics and PubHlth 640 - Intermediate Biostatistics. Minimal mathematical background is required. Familiarity with algebra is generally sufficient. The goal of PubHlth 540 is basic statistical literacy. It begins with a discussion of the ideas of variability in nature and the tools we use for its description. The distinctions between systematic versus chance variability are detailed. Concepts in simple random sampling and sampling distributions are introduced. Within this framework, you will learn selected methods of data description, estimation and hypothesis testing.

Topics include: graphical and numerical description, random sampling and selected probability models (the Bernoulli, binomial, and normal), sampling distributions, confidence interval estimation, and the basics of statistical hypothesis testing. If time permits, there will also be an introduction to simple linear regression and correlation.

Course Objectives and Outcome Competencies

Course Objectives: By the end of this course, you should be able to perform, interpret, and communicate the findings of selected simple statistical analyses of biological and health data, including description, confidence interval estimation and hypothesis testing.

 

Outcome Competencies:

The specific outcome competencies include, but are not limited to the following:

1. The selection and conduct of appropriate statistical analysis – Upon completion of this course, you will have learned the basics of choosing from among the various statistical methods when you want to summarize data, estimate population parameters, or perform a statistical hypothesis test. Specifically, you will have practice in these techniques in the one and two population settings under the assumption of either a normal or binomial population distribution sampling.

2. Integrating analysis strategies in biostatistics with principles and issues in epidemiology – You will have an understanding of the applicability of data description, estimation and hypothesis testing to epidemiology and, specifically, their interpretation with respect to confounding, effect modification, and bias.

3. Evaluation of basic statistical principles in published public health research – At the end of this course, you will have had practice in reading published examples of biostatistics. You will be encouraged to earn your 10% participation grade by selecting a published article from your own particular area of interest and writing a brief summary of its content.

4. Appreciating a conceptual framework that integrates techniques and methods in biostatistics – In this course, two conceptual frameworks are utilized. The first is the perspective that the principles and methods of epidemiologic research are an extension of the scientific method (and the goal of causal inference) to observational studies (and the challenges to causal inference that arise there!). The second conceptual framework is the idea that a statistical hypothesis test is a comparison of “signal” to “noise”.

(4) UNIT 6&7 Test is required
(5) There is NO TEST of Units 8 or 9.

Policy on Due Dates

I appreciate that we all have busy schedules and that, sometimes, deadlines are difficult to meet. Therefore, I have developed the following policy on late submissions. I will accept late submissions up to one week. Please be aware, however, that in considerationof your classmates, a late submission carries a 20 point penalty. Thus, if you know you cannot meet a due date, your best bet is to use the full week grace time!
