The first half of this Guide reviews general principles of statistics, and is not at all specific to GraphPad Prism. It includes discussions of some important issues that many statistical text books barely mention, including:
•The danger of using outlier tests with lognormal distributions and the problem of masking which can make it harder to find two outliers than to find one.
•Why it doesn't make sense to automate the decision to use a nonparametric test or not.
•A simple analogy to understand statistical power.
•A set of analysis checklists. Each checklist lists questions you should ask yourself before accepting the results of a statistical analysis.
The second half of the guide explains how to analyze data with Prism. Even so, much of the content explains the alternative analyses and helps you interpret the results. These sections will prove useful no matter which statistical program you use.
