Question

shoe size would best be used as the explanatory variable, and grade point average the response variable. what would you expect to see in the scatterplot? a. the scatterplot should have a positive, straight (linear), and strong correlation. b. the scatterplot should have no direction, no form, and a weak correlation. c. the scatterplot should have a negative, straight (linear), and strong correlation. d. the scatterplot should have a positive, curved, and strong correlation.

Explanation:

Shoe size and grade - point average are not related. There is no logical or causal link between physical shoe - size and academic performance. So, there should be no direction, no form, and a weak correlation in the scatter - plot.

Answer:

B. The scatterplot should have no direction, no form, and a weak correlation.
