The variation between groups is expressed by comparing each ,group mean, to the ,grand mean, 12.1.12 A fundamental relationship of ANOVA Notice that the deviation of an individual observation from the ,grand mean, can be expressed as follows:

Centering, In LME, you can use either of these to center your X variables. Which one should you use? If you care mainly about within-subjects effects or cross-level interactions: ,group mean centering, If you care mainly about between-subjects effects: ,grand mean centering, If you want to compare effects at different levels: ,group

There are three approaches that can be used, that is: no ,centering, (NC), ,grand,-,mean centering, (GMC), and cluster-,mean centering,. GMC is simply a linear transformation of the data, and leads to a model that is statistically equivalent to NC (cf. Kreft et al., 1995 ; Raudenbush and Bryk, 2002 ; …

The choice between ,grand,-,mean centering, and ,group,-,mean centering, depends on your theoretical thinking about processes. If you think that the absolute values of level 1 variable matter, then use ,grand,-,mean centering,.

Two of the most common approaches are grand-mean centering vs. group-mean (or within-cluster) centering (Bryk & Raudenbush, 1992; Enders & Tofighi, 2007). This latter approach could actively be impaired by standardizing the variable after applying the group-mean centering strategy, potentially leading to misinterpretation of the model effects.

Group,-,mean centering, – Difference with ,group mean, e.g. −. – Almost always needed for level-1 variablesin MLMs. – Isolates the level-1 effect. – Will change the interpretation of slopes and intercepts.
