Quizplus · Accepted Answer

The maximum length of the whiskers is usually defined as 1.5 times the interquartile range (IQR). This allows for the detection of outliers, which are data points that fall outside of the expected range of values. The IQR is calculated as the difference between the third quartile (Q3) and the first quartile (Q1).
