About Box Plots

A box plot (box-and-whisker plot) displays the distribution of data based on a five number summary.

Components:

  • Box: Extends from Q1 to Q3, containing the middle 50% of data
  • Median line: Shows the middle value inside the box
  • Whiskers: Extend to the smallest and largest values within 1.5×IQR from the quartiles
  • Outliers: Points beyond the whiskers

Box plots are excellent for comparing distributions and identifying outliers.
