Display Options
Select an option from the most common alpha levels or specify
any level with the Other selection. Changing the alpha level
modifies the upper and lower decision limits.
For ANOM, creates a report showing group means and decision
limits.
• For ANOM with Transformed Ranks, creates a report
showing group mean transformed ranks and decision limits.
• For ANOM for Variances, creates a report showing group
standard deviations (or variances) and decision limits.
• For ANOM for Variances with Levene (ADM), creates a
report showing group mean ADMs and decision limits.
(Only for ANOM for Variances) Changes the scale of the y-axis
from standard deviations to variances.
Display options include the following:
• Show Decision Limits shows or hides decision limit lines.
• Show Decision Limit Shading shows or hides decision
limit shading.
• Show Center Line shows or hides the center line statistic.
• Show Needles shows or hides the needles.
Compare Means
Note: Another method for comparing means is ANOM. See “Analysis of Means Methods” on page 144.
Use the Compare Means options to perform multiple comparisons of group means. All of these methods use
pooled variance estimates for the means. Each Compare Means option adds comparison circles next to the
plot and specific reports to the report window. For details about comparison circles, see “Using Comparison
Circles” on page 148.
