2.2.2 The median incomes of females in each state of the United States, including the District of Columbia and Puerto Rico, are given in table #2.2.10 ("Median income of," 2013). Create a frequency distribution, relative frequency distribution, and cumulative frequency distribution using 7 classes.

Describe the shape and any findings you can from the graph. Both graphs are skewed to the right. Which means more females in 2013 made lower median salaries rather than the higher median salaries
