If we subtract the mean of the SWLS score for the sample from each participant's score, the mean of the resulting centered SWLS score is zero.
Documenting the results Lastly, the moderator will also display the solutions proposed by the participants during the discussion.
Centering involves subtracting the overall sample mean score from the original score; standardizing does the same followed by dividing by the overall sample standard deviation.
In this case, low reliability of the interaction term leads to low power; therefore, we may not be able to find the interaction effects between A and B that actually exist.
