1. ### Three-Way (2x2x2) Between-Subjects ANOVA in SPSS

I'm just wondering how I can decompose a significant 3-way interaction in SPSS (all three IVs are categorical) without splitting the file, so that my follow up degrees of freedoms in the follow up tests remain the same as the omnibus degrees of freedom?
2. ### IVs and moderator variables correlate in three-way interaction - problematic?

Hi everybody, let's assume I hypothesize: H1: A direct effect of X1 on Y H2: A direct effect of X2 on Y H3: A two-way interaction between X1 and X2 H4: A three-way interaction between X1, X2 and X3 H5: A three-way interaction between X1, X2 and X4 and run the following OLS regressions to test...

Hi, I am doing ANOVA using three fixed independent factors of which one is sex (two levels 'male' and 'female'), temperature (three levels: 1,2,3) and quality (two levels: good and bad) and I want to see the effect of these factors on dependent variable factors like life-span, weight and...
4. ### post hoc test for unequal sample size and variance

Hi.I have a three way and two way significant interaction in ANOVA but the sample size and variance of each group is different. What post-hoc test can I use ? Due to unequal variance I had to rule out Tukey -Kramer test. Thanks:wave:
5. ### Three-way ANOVA interaction: Post-Hoc tests

Hi There, I have a 2x3x4 repeated measured anova. I have a significant 3-way interaction, and I want to make sure that I am using the correct post hoc comparisons and not violating any key statistics theory. If we consider my 2x3x4 RM ANOVA to be AxBxC. With the significant 3-way interaction...
6. ### How Do I Create a line graph for a three-way interaction with a continuous variable?

I ran a 2 (Time 1, Time 2) X 2 (Prime Type: Secure, Neutral), X (Prime Technique: Implicit, Explicit) X Covariate (Anxiety) Mixed-Subjects ANOVA examining the change in state psychopathy. I have a significant three-way interaction (Time by Type by Anxiety). Anxiety is a continuous variable...
7. ### Following up a 3-way interaction in a mixed ANOVA using LMATRIX and MMATRIX in SPSS
