Describe the Difference Between a Main Effect and an Interaction

Question

Examlex · Accepted Answer

The Answer is A main effect refers to the overall impact of one independent variable on the dependent variable, without considering the influence of any other variables. In other words, it shows the average effect of one variable across all levels of another variable. For example, in a study examining the effects of both gender and age on job performance, the main effect of gender would show the average difference in job performance between males and females, regardless of age.

On the other hand, an interaction effect occurs when the effect of one independent variable on the dependent variable changes depending on the level of another independent variable. In other words, the impact of one variable is not consistent across different levels of another variable. Using the same example, an interaction effect between gender and age would indicate that the effect of gender on job performance varies depending on the age of the individuals. This means that the difference in job performance between males and females is not the same for all age groups.

In summary, the main effect shows the overall impact of one variable, while an interaction effect demonstrates how the effect of one variable changes depending on the level of another variable. Both are important in understanding the complex relationships between variables in research.
