IQR: the data distribution is skewed
Since IQR is more resistant to outliers and the dataset has a wide range of values, including some that are significantly higher than the rest, it is more appropriate to use IQR to describe 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 IQ or MAD-best describes the spread of the dataset?
(1 point)
O IQR, the data distribution is symmetrical
