The table below presents the homicide rates for the 50 states for two different years.

a. Calculate the mean and median rates for both years. Remember to rank-order the states before finding the median.

b. Compare the mean and median for each year separately. Which is the higher value? Why?

c. If you removed Louisiana (the state with the highest rate in both years) from the distributions and recalculated, what would happen to the mean? To the median? Why?

d. If you removed North Dakota (the state with the lowest rate) from the 1994 distribution and New Hampshire (the state with the lowest rate) from the 2009 distribution and recalculated, what would happen to the means and medians for both years? Why?
