A × B Interaction

Generate a problem to see options.

3. Find the F Critical Values

F_crit(df_A, df_Error) — Factor A

F_crit(df_B, df_Error) — Factor B

F_crit(df_A×B, df_Error) — A×B

4. Determine Statistical Significance

Factor A

Reject H₀ (Factor A effect is significant) Fail to reject H₀ (not significant)

Factor B

Reject H₀ (Factor B effect is significant) Fail to reject H₀ (not significant)

A × B Interaction

Reject H₀ (interaction is significant) Fail to reject H₀ (not significant)

5. Compute η² (Effect Size)

η²_A = SS_A / (SS_Total-SS_B-SS_AxB)

η²_B = SS_B / (SS_Total-SS_A-SS_AxB)

η²_A×B = SS_A×B / (SS_Total-SS_A-SS_B)
