Two-way repeated measures

Answer 1

Answer 2

• Output of 3 effects:
  
  • Significance of 2 main effects
  • Significance of interaction effect

Question 3

Mixed designs

Answer 3

• Always at least 2 IVs:
  
  • One or more IVs has repeated measures (within-subject) measures
  • One or more has independent (between-group) measures

  • between-groups → homogeneity of variance
