Analysis of a Latin Square Experiment - Means Tab

Analyzing Latin Square Design

Select the Means tab in the Analysis of a Latin Square Experiment dialog box to access options to view the marginal means.

Marginal means
Click the Marginal means button to display a spreadsheet with the marginal means, parameter estimates, and standard deviations for each level for each factor. The parameter estimates can be interpreted as deviations of the means from the overall mean (m) for the respective levels of the respective factors. For example, a parameter estimate of lA1 = .5 for level 1 of factor A means that, all other things being equal, setting this factor to this setting resulted in a mean of m + lA1.
Means plot
Click the Means plot button to display a plot of means for each factor in the design. In this plot, the optimum setting for each factor can be easily identified.
