First in a series on statistics in biology looking at how to use the t-test, Chi-squared test and Spearman rank correlation test for A level biology. In this first episode I discuss: 1. The three tests and what each is used for 2. How to decide which test to use 3. The general procedure for doing all the tests In the following episodes I will use examples to show how to each type of test.
