About Capability Plots

Capability plots use box-and-whisker visualization to show which data points are most likely to meet the design specifications.

Each whisker is at the minimum and maximum value, or it is at three standard deviations above and below the mean, whichever is closer to the mean. The mean is the line in the middle of the box. The box extends to one standard deviation above and below the mean.
