What is a simple effect analysis?
when an analysis of variance or multiple regression analysis has identified an interaction effect among two independent variables, an examination of the effect of one variable at one level of the other variable.
What does interaction effect mean?
An interaction effect is the simultaneous effect of two or more independent variables on at least one dependent variable in which their joint effect is significantly greater (or significantly less) than the sum of the parts. Further, it helps explain more of the variability in the dependent variable.

How do you find the main effect?
The main effect of type of task is assessed by computing the mean for the two levels of type of task averaging across all three levels of dosage. The mean for the simple task is: (32 + 25 + 21)/3 = 26 and the mean for the complex task is: (80 + 91 + 95)/3 = 86.67.
How do you test for main effects?
To determine whether there is a main effect of student age, you would need to test whether the 2.5-point difference is greater than you would expect by chance. each mean by the number of scores that contributed to the mean, added those two weighted means together, and then divided by the total number of scores.
What does a non significant interaction mean?
1. 2. It means the joint effect of A and B is not statistically higher than the sum of both effects individually. Your response still depend on variable A and B, but the model including their joint effects are statistically not significant away from a model with only the fixed effects.
What is an interaction effect example?
An interaction effect happens when one explanatory variable interacts with another explanatory variable on a response variable. For example, let’s say you were studying the effects of a diet drink and a diet pill (the explanatory variables) on weight loss.
What is main effect and interaction effect?
In statistics, main effect is the effect of one of just one of the independent variables on the dependent variable. There will always be the same number of main effects as independent variables. An interaction effect occurs if there is an interaction between the independent variables that affect the dependent variable.
What does interaction mean?

What is an example of interaction?

What are different types of interaction?

What are the four types of interaction?
According to the present understanding, there are four fundamental interactions or forces: gravitation, electromagnetism, the weak interaction, and the strong interaction. Their magnitude and behaviour vary greatly, as described in the table below.
