In a two-factor ANOVA, a significant interaction means that at least one of the main effects is also significant.
True or False?
Homework Answers
Given statement, " In a two-factor ANOVA, a significant interaction means that at least one of the main effects is also significant." is False
Note: In a two-way ANOVA with interaction, a significant interaction term indicates that both factors have a combined effect on the response variable. And also it doesn't means that both factor have significant main effects.
