Overview of task

This is an introduction to working with the Normal distribution – it starts with a problem likely to interest students.

Strand

Statistics

Prior knowledge

Students need to be familiar with the statistics: mean, variance and standard deviation.

Relevance to Core Maths qualifications

•AQA

•C&G

•Eduqas

•Pearson / Edexcel

•OCR

Suggested approaches

This is a whole class task with opportunity for group discussion, as it starts with a problem. There is individual practice for determining probabilities/areas under a Normal distribution. As well as using tables for determining areas under a Normal distribution, you may wish to use calculators with built-in values.

Resources/documentation

There is a PowerPoint presentation and interactive whiteboard resources.

Relevant digital technologies

You could introduce the use of calculators with appropriate statistical functionality to determine areas under the Normal distribution.

Possible extensions

The ‘chicken and egg’ problem follows.
