This is the second of seven linked lessons that provide the basis for an extended piece of statistical work based on population data. All seven lessons make use of population data sets available from the Population Research Bureau. This lesson explores various methods of sampling, and uses these to select samples of countries for further analysis.

Overview of task

This is the second of seven linked lessons that provide the basis for an extended piece of statistical work based on population data. All seven lessons make use of population data sets available from the Population Research Bureau. This lesson explores various methods of sampling, and uses these to select samples of countries for further analysis.

Mathematical strand

Statistics

Prior knowledge

This sequence of lessons should be accessible by all Core Maths students. Students need a good knowledge of summary statistics and graphical representations, as covered at GCSE level, and should have completed the previous lesson on the Demographic Transition Model.

Relevance to Core Maths qualifications

•AQA

•C&G

•Eduqas

•Pearson / Edexcel

•OCR

Suggested approaches

Full teacher guidance is provided in the notes to the accompanying PowerPoint presentation. This activity provides a good starting point for classroom discussion of the different sampling methods and their suitability, and for paired or group work.

Resources/documentation

The annual World Population Data Sheet provides a wealth of useful data, which is referred to throughout this lesson. The Student resource sheet includes answer sheets for the presentation questions in all of the seven lessons; if students are using spreadsheets they can manage without the resource sheet; otherwise, it will definitely be needed. An assessment activity is also supplied as a separate worksheet.

Relevant digital technologies

Students will need access to a spreadsheet, and would benefit from using some of the powerful data visualisation tools available on the internet. As well as the Population Research Bureau site cited above, Gap Minder is an indispensible resource.

Possible extensions

Extension suggestions are provided in the PowerPoint presentation.
