AQA Spec | Year 1 & 2 | Maths for Biologists Series
A complete, ready-to-use lesson covering the Student’s t-test for A Level Biology, guiding students through one of the most important and often challenging statistical tests required for exam success.
This lesson provides a clear, step-by-step introduction to the purpose of the Student’s t-test, before walking students through how to carry out the calculation using a structured, click-by-click interactive PowerPoint. Students are then supported in developing deeper understanding by learning how to interpret calculated values, apply degrees of freedom, and determine statistical significance in a biological context.
Designed to support both teaching and independent learning, this resource includes structured explanations, worked examples, and opportunities for consolidation and practice.
