Question

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

• A. The one with higher class width
• B. The one with lower class width
• C. Both have same density
• D. Can't say

Answer 1

Answer: (C)

Both have same density

The density of observations doesn't depend upon the widths of the bars in the histogram. The height of the bar is proportional to its frequency. So, both the bars will have the same density of observations.
