MAD; the data distribution has outliers
The dataset has a few values that are significantly higher than the rest, indicating the presence of outliers. In this case, using the Mean Absolute Deviation (MAD) would be more appropriate for describing the spread of 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?
