- Section A:
- First scatter plot: A. Positive correlation
- Second scatter plot: B. Zero correlation
- Third scatter plot: C. Negative correlation
- Section B:
- First scatter plot: C. Perfect negative correlation
- Second scatter plot: D. Strong positive correlation
- Third scatter plot: A. Weak negative correlation
- Fourth scatter plot: B. Weak positive correlation
- Section C:
- First scatter plot: C. Shoe size of people / IQ of people
- Second scatter plot: A. Height of people / Weight of people
- Third scatter plot: D. Amount in Pounds / Amount in Euros
- Fourth scatter plot: B. Age of a computer / Value of a computer
- a) The graph showing the weakest correlation is the one matching "Shoe size of people / IQ of people" (zero or very weak correlation).
- b) Another variable that could show a positive correlation with height is weight (as taller people often weigh more).
- c) A variable that could show a negative correlation with temperature is heating bill (as temperature decreases, heating costs typically increase).
