IQR; the data distribution is skewed
In this case, the Interquartile Range (IQR) would be a better measure of variability as the data distribution is skewed. MAD would not be as useful in this scenario since there are outliers in the data.
Maria surveyed girls on the amount (in $) they spent on a dress for the middle school spring fling:
79, 79, 79, 82, 84, 85, 89, 90, 99, 100, 100, 100, 129, 139, 155, 174, 189, 200, 209, 250
Which measure of variability—IQR or MAD—best describes the spread of the dataset?
