Question

In a histogram, the height of the rectangle shows:

• 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

Define a histogram

1. A graph, where a set of rectangles are represented as per the class intervals and the frequencies, is called a histogram.
2. The length of the rectangle runs along the $X$-axis and the breadth of the rectangle runs along the $Y$-axis.
3. The breadths of all the rectangles are the same and are called the class intervals.
4. The $X$-axis represents the class intervals and the $Y$-axis represents the frequencies.

So, in a histogram, the height of a rectangle shows the frequency of that particular class interval.

Hence, height of the rectangle in a histogram shows the frequency of the class, so, option (D) is the correct option.
