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?
Probing questions
Which graphs or diagrams were most useful for your survey and why?
Which graphs or diagrams were least useful and why?
How might you improve your table or graph?
Would a pie chart, a line graph or a scatter graph be a suitable way of representing your data? Why?
What do you look for in your data when deciding on possible suitable ways to represent it?
How would you go about exploring whether there might be a relationship between these two sets of data?
Can you think of another context that would have a similar correlation to this?
How do the graphs, charts and tables you have drawn and the calculations you have made justify your conclusions?
In what way do they confirm or negate your hypothesis?
