    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...

    MANOVA: What to do with a u-shaped DV?

    Hi, I am hoping to get some advice on my analysis for my MSc dissertation. I will try to keep it short but please let me know if there is more information I can provide to make the situation clearer. I have five conditions (IV): control, four experimental conditions. The experimental...

    IV problem of MANOVA

    Hi everybody, How can we know how many IVs can we put in MANOVA? I have 1 DV with 3 groups, and as IV, the neuropsychological test (CERAD) scores with 10 subtests (MMSE, TMT, BNT, verbal fluency etc.). Of course these subtests are correlated with each other. Do you think I should use...

    Analysis for a repeated measures design with covariate that varies over conditions?

    Hi all, I'm trying to find the correct analysis that will allow me to carry out the equivalent of a repeated measures MANCOVA with a covariate that varies over three conditions. Basically I have an experiment with 3 different types of task where every participant does every task in a...

    MANOVA vs. ANOVA

    Hi, I am trying to determine which of a number of variables differentiate between 3 groups. The groups were created based on cluster analysis, using a number of scales called the Emotional Availability (EA) Scales, that measure relationship quality between mothers and their children. I want...

    Scale Issue - MANOVA vs Kruskall Wallis

    Hello, In my dissertation, I asked people in the general population to complete a battery of team process measures based on an effective team (condition 1) or ineffective team (condition 2) that they had participated on. I asked each participant to describe the pattern of technology use...

    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...

    MANOVA design

    Being rusty, I would be grateful for a quick confirmation of MANOVA being an appropriate model: I have one dependent variable but 6 independent ones: group (3 levels), subjects per group (a variable number, between 11 and 110 subjects) and then the experimental variables: stimulus (3 levels)...

    Multiple MANOVAs - How to adjust post-hoc ANOVA p-values

    Hi everyone I have (multiple) dependent variables which I split into two groups. For each group I do a separate MANOVA (one group for metabolism-related genes and one group for immunity-related genes). I assume that if I do post-hoc ANOVAs for each dependent variable (i.e. gene), I will...

    Manova with within-subject and between-subject factors (no repeated measures!)

    hello, i need to do a manova with one within-subject factor (veracity) and two between-subject factors (type of speaker and type of presentation). However, it is NO repeated measures design! So how do I tell SPSS what to do? I have only found an option of entering within- and between-subject...

    Manova not significant, some Anova tests are. Are they valid?

    I"m doing my dissertation on recommendations made during a diagnostic procedure, so I have 19 dependent variables based on 8 diagnosis levels. When I ran SPSS it was not significant, does that mean that none of the relationships are significant? or could some of the individual Anova tests that...

    ANOVA or MANOVA

    Hi, I have a question on which statistical test to use for 2 separate problems: 1) I have 4 different groups, 1A, 1B, 2A and 2C and have 3 different response variables measured at several different times. However I am not interested in the behavior over time and want to treat them as...
