Question

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?

(1 point)
Responses

IQR; the data distribution is skewed
IQR; the data distribution is skewed

IQR; the data distribution is symmetrical
IQR; the data distribution is symmetrical

MAD; the data distribution has outliers
MAD; the data distribution has outliers

MAD; the data distribution is symmetrical

Answer 1

MAD; the data distribution has outliers

This is because MAD is less influenced by outliers compared to IQR, and the dataset contains some larger values such as 155, 174, 189, and 250 which could be considered outliers.
