Least Significant Difference Interval for Graph Builder Means

The graph builder currently includes options to plot standard deviation (SD) or standard error (SE) intervals around group means.  I'd like an option to plot "Least Significant Difference (LSD) " intervals around the group means.  These intervals are approximately 1.4*SE, and non-overlapping intervals show means that are (approximately) significantly different.  Many users interpret the current SD and SE limit to show statistical significance when they overlap; having an LSD options would provide better guidance. 

 

These intervals are currently available in several other statistical software packages.  They can be generated in the Fit Model platform (Means Plot), but many users only use Graph Builder as it's faster for them.

 

PS., Would also recommend using the pooled within-group SD for the LSD intervals.
