2D Box Plots - Mean/SE/1.96*SE

This box-whisker plot will show the mean (small box in the plot) of a category surrounded by a larger box (± 1 times the standard error).  If the distribution is normal, then the "whiskers" in this plot represent a "95% confidence interval" defined as the category mean ± 1.96 times the category standard deviation.

This option is available via Graphs of Input Data (see Box-Whisker by ...) and via the Graphs of Block Data custom graph options (e.g., Custom Graphs for Entire Column).  Box Plots can also be created with a variety of graph types and other options using the Graphs options from the Graphs menu, see Graphs menu graphs, 2D Box Plots, and 3D Box Plots.
