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?
What if pupils find this a barrier?
Pupils need to understand how to interpret graphs if they are to know how they could use a graph to assist an enquiry. For example, if a company making shoes has 2000 to manufacture, they need to know what the distribution of sizes is like in the population in order to determine how many each of size 6, 7, 8, 9 and 10 to make. The information could be gathered and a pie chart produced to show proportions.
Use exemplar material from pupils' GCSE coursework (AO4) to model the expectations.
