Box Plot

Shows data distribution through quartiles — minimum, first quartile, median, third quartile, and maximum. Each box spans Q1 to Q3 with a median line inside, and whiskers extend to the min and max values.

Best for

  • Comparing distributions across categories
  • Identifying outliers and data spread
  • Showing statistical summaries at a glance

Avoid when

  • Audience is unfamiliar with statistical concepts
  • You need to show individual data points — use a strip or bee swarm plot
  • Data has only a few values per category
