If the omnibus analysis of variance for a complex design reveals a statistically significant interaction effect,the source of the interaction effect may be identified using
A) null comparisons.
B) simple main effects analyses.
C) correlational analyses.
D) complex comparisons.

Question

Quizplus · Accepted Answer

Simple main effects analyses are the appropriate method for investigating the source of a statistically significant interaction effect. This analysis examines the effect of one independent variable at each level of the other independent variable involved in the interaction, allowing for a more detailed understanding of the relationship between the variables. Null comparisons, correlational analyses, and complex comparisons are not appropriate for identifying the source of an interaction effect.
