First -- Choose the right test! [return to Table of Contents]

There are a bewildering number of statistical analyses out there, and choosing the right one for a particular set of data can be a daunting task. Here are some web pages that can help:

  1. "Selecting Statistics", by Bill Trochim (Cornell). This is an interactive set of web pages to help you select the right kind of analysis to perform on your data. It asks you a simple series of questions about your data (how many variables, etc.), then makes recommendations about the best test to perform.
  2. Choosing a Statistical Test, Chapter 37 of Dr. Harvey Motulsky's book Intuitive Biotatistics.
  3. The very extensive test-selection routine used in Dr. Robert Knodt's MODSTAT statistical package.
