IQR; the data distribution is skewed
The IQR (Interquartile Range) would be the best measure of variability for this dataset because the data distribution is skewed, with a few high values at the upper end of the range. The MAD (Mean Absolute Deviation) may not accurately capture the spread of the data in this case.
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?
