      Crucial EDA Principle:

      The Mean is sensitive to extreme values because it minimizes squared errors ($\sum (x_i - \mu)^2$). A single massive outlier drags the mean significantly toward itself. In contrast, the Median and IQR are rank-based order statistics that remain completely unaffected by the extreme magnitude of outliers.
