Labeled Box Plot & Five-Number Summary Example

This example turns on median, quartile, whisker, and mean annotations so the structure of the box-and-whisker plot is explicit. The Chart panel also calculates the observed minimum and maximum, Q1, median, mean, Q3, IQR, whisker range, count, and outlier count.

How to structure the data

  • 01Paste raw numeric observations and keep them in one group for a single labeled box plot.
  • 02Vizvero calculates quartiles by linear interpolation and Tukey whiskers with the 1.5×IQR rule.
  • 03The observed min and max can differ from the whisker endpoints when potential outliers are present.

What this example shows

Label Q1, median, Q3, whisker endpoints, and the mean while viewing the calculated statistics.

Five-number summary

The traditional five-number summary is minimum, Q1, median, Q3, and maximum. In a modified box plot, whisker endpoints can differ from the observed min and max because potential outliers are drawn separately.
