    Are the parametric analyses appropriate?

    In an experimental study, the aesthetic value (independent var) of a picture is manipulated into (low and high quality). "Low Quality" -- to make it look less appealing; and "High Quality" to make it look "very attractive." I want to examine the effect of "Low" and "High" Quality images on the...

    Non-Normality - Measuring of stereotypes

    Hello :) I'm researching a moderated mediation (2x2) with two mediators. To test my MANOVA and moderated mediation I have to check the normality assumption of errors (residuals). My sample size is 400. 1.) One of my mediators has a non-normality distribution of residuals (which I think is...

    Meta-analysis to compare 3 randomized control trials?

    I'm proposing to evaluate an outcome in three completed randomized controlled trials. The primary goal is to analyze a new outcome in each data set separately (i.e., 3 separate papers). A secondary aim is to compare across the three trials to see which intervention type was most effective...

    Regression following MANOVA results

    Hi Stats Gurus, This question is about a regression analysis that I want to run, but I am not too familiar with this type of analysis. I have conducted MANOVAs to isolate variables that are significant out of the ones that were theoretically relevant for my analysis. I would now like to...

    Demographic data and MANOVA

    I have a set of demographic data including countries categorised into 6 geographical regions and I want to see how these regions differ depending on life expectancy and GNP. I believe that I will need to use MANOVA since my DVs (life expectancy and GNP) are continuous and my IV is categorical...

    Hotelling's Trace v. Hotelling's T^2- Why make the move?

    Hello, I am writing a dissertation and my chair wants me to convert Hotelling's Trace (resulting from my MANOVA) into Hotelling's T^2. No problem to actually do, but what I cannot find in research, and what my chair won't tell me, is why I would do this. The Trace shows the sum of the SSM/SSR...
