Question

two histograms showing the number of pets owned by boys and girls in a science class are each skewed left. which measure of variability should be used to describe the data? mean median standard deviation interquartile range

Explanation:

When data is skewed (either left - skewed or right - skewed), the mean and standard deviation are affected by extreme values. The median is a measure of central tendency, not variability. The interquartile range (IQR) is a robust measure of variability that is not affected by extreme values in skewed data.

Answer:

D. interquartile range
