Statistical tests in A-Level biology (AQA)

A complete summary of all three main statistical tests required for AQA Biology: 95% confidence limits and standard error, spearman rank and chi-squared. The worksheet focuses on the basic routine of each test rather than getting bogged down with detailed explanations of the theory behind them. A useful resource to give to students as a summary once statistical tests have been taught. Each summary provides data for students to analyse and practice each test. There is also a quick quiz at the start, whereby students need to select the appropriate statistical test for each investigation.

Key words: Statistical tests, 95% confidence limits, standard error, chi-squared, spearman rank, maths, degrees of freedom, critical value, probablity, null hypothesis
