• Size it up grasp the most common statistical techniques for comparing groups: t tests, ANOVAs, chi–square tests, and Fisher Exact tests
• Let′s regress learn how to test for and quantify the relationship between two or more variables, from a simple straight–line regression to multiple, logistic, nonlinear, and other kinds of regression
• Survive and thrive see how to calculate survival curves, test for a difference in survival between two or more groups of subjects, and apply the methods of regression analysis to survival data
Open the book and find:
• Basic math and statistical formulas, concepts, and techniques you need to know
• The big picture of clinical research
• How to summarize and graph data
