Three scatter graphs are shown below. 

Data is collected for three different investigations. These are:

(i) The number of ice-creams sold per hour by an ice-cream vendor and the temperature during that hour 

(ii) Pupils’ maths test results and their English test results 

(iii) The value of a car and its age.

a. Match each scatter graph to the likely data from each investigation. Justify your choices. 

b. Describe three different investigations which you think are likely to produce similar scatter graphs to the ones shown above. Justify your choices.
