When using histograms to compare two data sets, it is sometimes difficult to make comparisons by looking
Question:
When using histograms to compare two data sets, it is sometimes difficult to make comparisons by looking back and forth between the two histograms. A back-to-back relative frequency histogram has a format that makes the comparison much easier. Instead of frequencies, we should use relative frequencies (percentages or proportions) so that the comparisons are not difficult when there are different sample sizes. Use the relative frequency distributions of the ages of Oscarwinning actresses and actors from Exercise 19 in Section 2-1 on page 49, and complete the back-to-back relative frequency histograms shown below. Then use the result to compare the two data sets.
