Question

sylvia wants to construct a display to represent her sons height each year as he was growing up. which type of display would be most appropriate and why? a. a scatter plot would be most appropriate because the data is an association between two variables. b. a line graph would be most appropriate because the data is an association between two variables. c. a line graph would be most appropriate because the data shows a trend over time. d. a scatter plot would be most appropriate because the data shows a trend over time.

Explanation:

A line graph is used to show trends over time. Sylvia is tracking her son's height each year (which is data over time). A scatter - plot shows the relationship (association) between two variables. Since the data is about height over time (a trend over time), a line graph is appropriate.

Answer:

C. A line graph would be most appropriate because the data shows a trend over time.
