Question

The height of a rectangle in a histogram shows the

• A. Width of the class
• B. Upper limit of the class
• C. Lower limit of the class
• D. Frequency of the class

Answer 1

The correct option is D

Frequency of the class

A histogram is a graphical representation of a grouped frequency distribution with continuous classes. It is an area diagram and can be defined as a set of rectangles with bases along with the intervals between class boundaries and with areas proportional to frequencies in the corresponding classes. A histogram is a diagram involving rectangles whose area is proportional to the frequency of a variable and width is equal to the class interval.

Hence, option d is correct answer.
