The primary difference between a bar graph and a histogram is
a. the bar graph is more useful for displaying continuous data, while the histogram is better for displaying discrete data.
b. the bars in a histogram do not touch, while those in a bar graph do touch.
c. none of these statements are correct.
d. the bars in a bar graph do not touch, while those in a histogram do touch.

D. The bars in a bar graph do not touch, while those in a histogram do touch.

Explanation:

A histogram is used for continuous data, while bar graphs show discrete data, so the first option is already out of the picture.

Bars in a bar graph do not touch each other, while histogram bars have no gap in between, so the answer would be D.

Another is histograms are used for numerical data, while bar graphs are used for categorical.
