This is a revision lesson. It is designed to help students to calculate and report the findings of the sign test as well as define and answer questions relating to type I and type 2 errors. This is a fully resourced lesson with both a presentation and student handout.

The lesson starts with definitions of key terms e.g. statistical testing and probability. The powerpoint then provides a step-by-step demonstration of how to calculate the sign test and how to report the findings of the statistical test. Then students are given 2 examples of studies which require them to calculate the sign test and report their findings. An extension task is provided which requires students to report the findings of 3 other studies using the sign test.

Finally students are given a definition of a type 1 and type 2 error, with 3 exam-style questions to complete(suggested answers in the ‘notes’ box on the powerpoint.
