Question

Which best describes the purpose of bar graphs?

Answer 1

The right answer is They compare quantities for particular categories.

The bar graph is composed of horizontal bands. The categories are presented on the ordinate (Y axis - vertical). The length of each bar is measured by the values arranged on the abscissa (X axis - horizontal).

It draws attention to the comparison of values rather than a period followed by time (as in the case of the bar chart).

Answer 2

B. They compare quantities for particular categories

Bar graphs are mainly used to show comparisons between categories.
