Examples

Interaksi 2×2

Problem:

Faktor A (2 level), Faktor B (2 level), n=10 per sel. ANOVA?

Solution:
  1. 1.Calculate SS_A, SS_B, SS_AB, SS_Within
  2. 2.Calculate MS = SS/df
  3. 3.F = MS/MSE
Result:F_A=5.2 (p<0.05), F_B=3.1 (p>0.05)

Faktor A significant, Faktor B and interaksi tidak significant.
