Step 9 Objective
Select, construct and modify, on paper and using ICT, suitable graphical representations to progress an enquiry, including scatter graphs to develop further understanding of correlation.
Examine critically the results of a statistical enquiry, and justify the choice of statistical representation in written presentations.
- Examples of what pupils should
know and be able to do - Probing questions
- What if pupils find
this a barrier?
Examples of what pupils should know and be able to do
Use a spreadsheet to construct charts in order to compare two distributions.
Draw a scatter graph to determine a connection between two aspects, e.g. a scatter graph of two judges' scores awarded in a competition to determine whether they agree with one another.
Pupils should be able to carry out a survey from setting the hypothesis through to interpretation of the results and reflection on the outcome and the survey itself.
