The argument / response that is provided by the editor in favor of always reporting that main effect even when the interaction is present (demonstrating a counter example): "Yes, it is imperative to defend a statement purported to describe data with a statistic.

**How to explain when Main Effect and Interaction are not**

how would you interpret it, say, if your coefficient for the interaction effect Bacteria*Sun were negative, such that it “cancelled out” the main effect in a sense? E.g., if the coefficient for Bacteria is 4.2, and for Bacteria*Sun it is -4.2? If these coefficients were both significant, …... If b3 is negative, then it shows that the effect of X on Y will decrease (get smaller) as Z gets larger, and that the effect of Z on Y will decrease (get smaller) as X gets larger.

For example, let α = the main effect of A and β = the main effect of B. More specifically: More specifically: Says α 1 equals the mean for the population for all groups in the first level of factor A minus the mean of the total population of scores.... The main effects plot displays the means for each group within a categorical variable. Minitab creates the main effects plot by plotting the means for each value of a categorical variable. A line connects the points for each variable. Look at the line to determine whether a main effect is present

### 3/02/2014 · A short video explaining main effects and interactions in factorial ANOVA experiments.

- It is assumed that main effect A has a levels (and A = a-1 df), main effect B has b levels (and B = b-1 df), n is the sample size of each treatment, and N = abn is the total sample size. Notice the overall degrees of freedom is once again one less than the total sample size.
- When two or more independent variables are involved in a research design, there is more to consider than simply the "main effect" of each of the independent variables (also termed "factors"). That is, the effect of one independent variable on the dependent variable of interest may not be the same at

- main effect of treatment. When ordinal interactions are significant, it is necessary to follow up the omnibus F-test with one of the focused comparison procedures described below. Usually, the main effects can also be interpreted and tested further when they are significant. However, when an interaction is significant and “disordinal”, main effects can not be sensibly interpreted. The
