ANOVA descriptives to include marginal totals #1225

  • Enhancement: When you tick the descriptives statistics for ANOVA you only get the means broken down by conditions, but not the marginal totals. When your interaction is not significant you want to be able to inspect the marginal totals.
  • Purpose: I'm teaching my students in an introductory course to always report a full table when they run an ANOVA. Now they have to do a separate descriptives analysis.

Describe the solution you'd like
It would be great if the marginal totals could be implemented in the descriptives statistics output table in the ANOVA itself. This saves time and is less error prone compared to copying and combining multiple tables.

Describe alternatives you've considered
Do this manually by adding a separate descriptive analysis using the split function to get the marginal totals of a main effect.

Additional context

@tomtomme there is a difference between descriptive means and the estimated marginal means - in balanced designs these are the same, but in unbalanced designs these might differ. I will look into adding a checkbox next to descriptives with something like "include marginal totals".
