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 (in this case, left - skewed), the interquartile range (IQR) is a better measure of variability. The mean and standard deviation are affected by outliers in skewed data. The median is a measure of central tendency, not variability. The IQR represents the range of the middle 50% of the data and is less affected by skewness and outliers.

Answer:

interquartile range
