Question

Explanation:

Box plots display the minimum, first quartile (\(Q_1\)), median (\(Q_2\)), third quartile (\(Q_3\)), and maximum of a data set. The inter - quartile range (IQR) is calculated as \(IQR = Q_3 - Q_1\). Standard deviation and mean are not directly shown on a box plot. The median is a measure of central tendency (not variability) shown on the box plot. Since the box part of the box - plot represents the inter - quartile range (the range between \(Q_1\) and \(Q_3\)), we can compare the inter - quartile range using box plots.

Answer:
