Question

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

Explanation:

Mean and median are measures of central - tendency, not variability. Standard deviation and inter - quartile range are measures of variability. Standard deviation is used when the data is normally distributed, and inter - quartile range is more robust to outliers. Since histograms can show non - normal distributions and potential outliers, the inter - quartile range is a good choice to describe the variability of the data.

Answer:

interquartile range
