What pattern of results should be obtained if the medication works as predicted? A significant main effect for factor A (medication) A significant interaction A significant main effect for factor A and a significant interaction None of the above The following table shows the results of a two factor analysis of variance with 2 levels of factor A, 3 levels of factor B, and a separate sample of n = 5 participants in each of the treatment conditions. Note that several values are missing in the table. What is the missing value for the F-ratio for the AxB interaction? 2 4 8 16.1Explanation / Answer
