This lesson guides students through the use of the student’s t-test (both Paired and Unpaired). It is fully-resourced with a detailed PowerPoint with worked examples and accompanying student work booklet that have been designed to cover this aspect of the A-level Biology specification.

The lesson includes a step-by-step guide that demonstrates how students should select an appropriate statistical test (from Chi squared, Spearman’s rank, Student’s t-test and paired t-test). The PowerPoint contains worked examples of how to carry out a paired and unpaired Student’s t tests from stating a null hypothesis, carrying out the statistic, how to find a critical value, what that means, compare the critical value with the statistical value, reject or accept the null hypothesis and write a conclusion.

The accompanying student booklet contains examination questions to consolidate the students’ understanding and worked answers are provided in the PowerPoint and also in an accompanying teacher version of the workbook.

This resource also contains an interactive Excel Spreadsheet designed to support students and educators in mastering hypothesis testing using the Student’s t-test. This includes a Paired and Unpaired t-test calculator with worked examples. Enter your own data and the spreadsheet automatically calculates the p-value! There is also a lookup table of critical t-values.
