This unit develops pupil's range of strategies for examining data by introducing the concept of the mean average. They will learn to calculate the mean average of a set of data and explain how it changes when the total value or number of values changes in the set. Pupils use the mean average to make comparisons and also explain when the mean is not appropriate for comparing data. This will lead on to using other ways of summarising data in the future.
Prior knowledge requirements
- Add and total a data set
- Divide a total equally
- Understand fair share concept
