The two data sets below show the approximate number of gallons of gasoline Josie and Olivia put into their cars the last 10 times they filled their gas tanks. A dot plot titled josie's Gasoline (gallons). The number line goes from 8 to 12. There are 2 dots above 8, 2 above 9, 6 above 10, and 0 above 11 and 12. A dot plot titled Olivia's Gasoline (gallons). The number line goes from 8 to 12. There are 0 dots above 8 and 9, 6 above 10, 3 above 11, and 1 above 12. Which measure of variability would most accurately compare the two data sets and why? the MAD, because the data points in Olivia’s set appear to be clustered near the beginning of the set the MAD, because the data points in both sets appear to be evenly distributed the IQR, because the data points in each set appear to be clustered near either the beginning or the end of each set the IQR, because the data points appear to be evenly distributed
