Detect outliers in a data set using the 1.5 × IQR rule.

How are Outliers Detected?

The 1.5 × IQR rule identifies outliers as values below Q1 - 1.5·IQR or above Q3 + 1.5·IQR, where IQR = Q3 - Q1. This method is based on the box plot and is robust because quartiles are resistant to extreme values. Values outside these fences are considered potential outliers.
