The course describes important biostatistical tools followed by a discussion of useful analytic strategies and how they work to distill messages from data.

Begins with a brief review of statistical estimation and

probability distributions. Also included is an introduction to bootstrap methods of statistical estimation. Then, confidence intervals are explored in detail. The analysis of two of

the most common and important biostatistical/epidemiological tools, namely 2 by 2 tables and 2 by k tables, follows. The roll of a variety of issues such as confounding variables, interaction, bias and independence, key elements in many statistical applications, are an additional focus of these discussions. Weighted averages are discussed particularly in the context of combining tables and estimates.

Learning Objectives:

Upon successfully completing this course, students will be able to:

  1. Understand and interpret confidence intervals in a variety of situations
  2. Understand the application of relative risk and odds ratio statistics particularly applied to 2 by 2 tables and 2 by k tables
  3. Understand rigorously the biostatistical/epidemiological concepts, precision, accuracy, independence, bias and confounding, in the context of the analysis of tables
  4. Use extremely simple and comprehensive bootstrap estimation methods
