theShapiro-Wilk normality test. For the sample sizes at hand, however, none of these are very useful anyway. A more thorough interpretation of the output for this analysis is presented inSPSS - One Way ANOVA with Post Hoc Tests Example. ...

"subject", is merely to remind you there is one row per subject. The next three columns, "lowcaff", "medcaff" and "highcaff", contain each subject's memory-test score for the low-, medium- and high-caffeine consumption conditions respectively. The final column, "sex", tells SPSS the...
Two-way ANOVA is a hypothesis test that allows you to compare group means. Like all hypothesis tests, two-way ANOVA usessampledata to infer the properties of an entirepopulation. In this post, I provide step-by-step instructions for using Excel to perform two factor ANOVA and then interpret...
• However, interpretation depends on common sense, and should adhere to theoretical considerations • If main effects are meaningful, then it makes sense to talk about them, whether or not an interaction is statistically significant or not • To help you interpret results, test simple effects...
Firstly, do I have to demean the covariates, before feeding them into (the) SPSS (multivariate general linear model)? Secondly, is Levene’s Test of Equality of Error Variances the test I need to do to check if the variances are sufficiently similar to perform the ANCOVA on? Lastly, ass...

The presence of interaction implies that the factor effects are not additive and complicates the interpretation of the results!? The difference in response between the levels of one factor is not the same at all levels of the other factor. This is called Interaction effect. responseresponseLevel...
