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

Answer

Explanation:

Step1: Recall data - measure relationship

When data is skewed, mean and standard - deviation are affected by outliers. Median is a measure of central tendency, not variability.

Step2: Identify appropriate variability measure

Interquartile range (IQR) is a robust measure of variability and is not affected by outliers. It is suitable for skewed data.

Answer:

interquartile range
