Question

If two bars in a histogram have unequal widths but the same height, then which class interval will have a higher number of observations?

• A. can't say
• B. The one with lower class width
• C. The one with higher class width
• D. Both have same number of observations

Answer 1

The correct option is C

The one with higher class width

Since the area of the rectangle in the histogram is proportional to the frequency so if the height of 2 bars are equal then the one with the greater width has a higher frequency
