Worksheet on scatter plots and correlation, featuring sections to match diagrams with descriptions and data sets, and questions about correlation.

Final Answer:
Section A:
1st graph → A. Positive correlation
2nd graph → C. Negative correlation
3rd graph → B. Zero correlation

Section B:
1st graph → C. Perfect negative correlation
2nd graph → D. Strong positive correlation
3rd graph → A. Weak negative correlation
4th graph → B. Weak positive correlation

Section C:
1st graph → C. Shoe size of people / IQ of people
2nd graph → A. Height of people / Weight of people
3rd graph → D. Amount in Pounds / Amount in Euros
4th graph → B. Age of a computer / Value of a computer

a) The graph showing the weakest correlation is the one with points scattered all over (zero correlation).
b) An example of a variable that could show a positive correlation with height is “arm span” or “shoe size.”
c) An example of a variable that could show a negative correlation with temperature is “heater usage” or “hot chocolate sales.”
