Students learn how to estimate the mean average from data in a grouped frequency table. As learning progresses they estimate the mean from data presented as a histogram. An I.C.T. lesson is built in through the provision of a Microsoft Excel spreadsheet.
Differentiated Learning Objectives
- All students should be able to calculate the mean from grouped data.
- Most students should be able to calculate the mean from a Histogram with equal class widths.
