Question

which type of graph is best suited for relating data from two different variables like the number of pounds people are overweight versus the number of hours they spend watching television per day?
a. box - and - whisker plot
b. line graph
c. scatter plot
d. histogram

Explanation:

A scatter plot is used to show the relationship (correlation) between two quantitative variables. Here, "pounds overweight" and "hours watching TV" are two variables, so a scatter plot is best. A box - and - whisker plot shows distribution of a single variable, a line graph is for showing change over time (or continuous data with a trend), and a histogram shows frequency distribution of a single variable.

Answer:

C. scatter plot
