Question

In a hypothetical sample of 20 people the amounts of money with them were found to be as follows:

114, 108, 100, 98, 101, 109, 117, 119, 126, 131, 136, 143, 156, 168, 182, 195, 207, 219, 235, 118.

Draw the histogram of the frequency distribution (taking one of the class intervals as 50-100).

Answer 1

Class interval	Frequency
50 - 100	2
100 - 150	11
150 - 200	4
200 - 250	3

By drawing class interval on ‘x’ axis and frequency on ‘y’ axis. The height of histogram shows the frequency for particular class interval.
