How can the effects of interaction be investigated in a two-way ANOVA?

  • By calculating the F-statistic for each independent variable
  • By checking the interaction term in the ANOVA table
  • By conducting a one-way ANOVA
  • By conducting post-hoc tests
The effects of interaction in a two-way ANOVA can be investigated by examining the interaction term in the ANOVA table. If the p-value for the interaction term is significant, it suggests that the effect of one independent variable on the dependent variable depends on the level of the other independent variable. Post-hoc tests can then be conducted to investigate the interaction effects further.
