Some options might not appear unless specific conditions are met.

Means and Std Dev
Lists the following quantiles for each group:
• 0% (Minimum)
• 10%
• 25%
• 50% (Median)
• 75%
• 90%
• 100% (Maximum)
Activates Box Plots from the Display Options menu.
See “Quantiles” on page 137.
Fits means for each group and performs a one-way analysis of
variance to test if there are differences among the means. See
“Means/Anova and Means/Anova/Pooled t” on page 138.
The Means/Anova/Pooled t option appears only if the X
factor has two levels.
Gives summary statistics for each group. The standard errors for
the means use individual group standard deviations rather than
the pooled estimate of the standard deviation.
The plot now contains mean lines, error bars, and standard
deviation lines. For a brief description of these elements, see
“Display Options” on page 136. For more details about these
elements, see “Mean Lines, Error Bars, and Standard Deviation
Lines” on page 144.
