Question

If we draw a histogram for the following frequency distribution, what will be the height of the bar for the class interval 15 - 30?

• A. 3
• B. 7
• C. 11
• D. 4

Answer 1

The correct option is B 7

When a frequency distribution table is depicted using histograms, the number of tally marks of a class interval is represented using the height of bars in the histogram.

Here, the frequency is 7 and hence the height of the bar is also 7 units.
