Reading the chart

What this example shows

  • The boxes barely overlap between levels, so level explains most of the variation in pay.
  • Spread widens as level rises — senior compensation is far less uniform than junior.
  • Two points sit outside the whiskers. Those are individual outliers by the 1.5×IQR rule, not data errors.
