Preamble
This open-ended task is probably best started by initially directing pupils to discuss how the problem might be attacked in small groups – stress the importance of this planning stage. After this, quickly take suggestions from the whole group. Depending on the response, share the work out between groups, or invite small groups to perform their calculations or draw their charts in front of the whole group. If time is scarce, the actual results may have to be given – if pupils decide they might be of use.
Encourage discussion about any conclusions drawn from two data sets – conclusions/decisions must always be backed up by logical reasons or numerical data.
Possible content
Using measures of location and the range to compare two sets of data.
Resources
Calculators, if pupils are to calculate the measures of location themselves.
