Several 3-way anovaANOVA vs one 4-way ANOVA

I have experiment leading to 4-way ANOVA:

  • 3 experimental groups.
  • participants in each group responded to 70 trials.
  • Reaction time as DV.
  • trials were divided into separate groups by full factorial design by three variables A,B and C.

I'm not sure what is the best way to analyze the data. I can run one 4-way ANOVA with (RT ~ group*A*B*C) or run three 3-way ANOVAs for each group separately (RT ~ A*B*C).

What is the best practice? Run one 4way4-way ANOVA, but harder to interpret, or run three 3-way ANOVAs and correct for multiple testing?

thanks Filip
