Outlier Detection The goal of outlier detection is to identify data points that are significantly different from the other observations in a dataset. In this response, we will use a statistical approach to detect outliers. Methodology We will use the following steps: Calculate the mean and standard deviation of each column. Use the interquartile range (IQR) method to identify outliers. Interquartile Range Method The IQR is the difference between the third quartile (Q3) and the first quartile (Q1).
