Do students who graduate from high school earn more money than students who do not? To find out, we took a random sample of 371 U. S. residents aged 18 and older. The educational level and total personal income of each person were recorded. The data for the 57 non-graduates (No) and the 314 graduates (Yes) are displayed in the relative frequency histograms. Would it be appropriate to use frequency histograms instead of relative frequency histograms in this setting? No, because one distribution has outliers while the other doesn’t. No, because there were many more graduates surveyed (314) than non-graduates (57). Yes, it would be appropriate to use frequency histograms instead of relative frequency histograms in this setting. No, because one distribution has a greater maximum relative frequency than the other. No, because the variability of the distributions differs drastically.
