  9. Checking for an Interaction • Using the line graph • Non parallel lines --> Possible Interaction • Crossover lines --> Definite Interaction • Matrix Table • If the difference between A1/A2 is different for each level of B, there is an interaction • If the difference between B1/B2 is different for each level of A, there is an interaction

  10. Checking for a Main Effect of A • Using the line graph • Both lines slope upward or both lines slope downward you have a Main Effect of A • To use the Matrix • Check the marginal means for A (here the row means)

  11. Checking for a Main Effect of B • Using the line graph • If line B1 is above line B2 or line B2 is above B1 you have a possible main effect of B • To use the Matrix • Compare the marginal means for B (here the column means)
