    I don't know how to report my results: did I use the wrong test?

    Oh you're right, I apologize. There is just one independent variable, that is the anxiety score. The multiple dependent variables include different experienced emotions during the night, sleep quality, and scores on other questionnaires.

    I don't know how to report my results: did I use the wrong test?

    Isn't that already what I did when running summary.aov(model)? Another way in which I have done the univariate tests as post-hoc, is using model2 = lm(cbind(dv1, dv2)~X). Then, when running summary(model2), this yields in exactly the same results as the summary.aov(model1). I also corrected...

    I don't know how to report my results: did I use the wrong test?

    Because there were many dependent variables to be tested, I decided to form groups of moderately correlated variables and perform multiple MANOVAs instead. I was under the impression that this would reduce the chance of Type I error, so that it would be better than performing multiple univariate...

    Multilevel analysis: Nesting variables to participants and comparing groups: what test to use?

    Do you mean I wouldn't have to use a multilevel approach? When using the anxiety score, which is available at the participant-level, and using this as a predictor for variables at the awakening-level, I think I need a two-level model of awakenings clustered in participants? Or will this result...

    Thank you! I will try to familiarize myself with a multilevel regression.

    Multilevel analysis: Nesting variables to participants and comparing groups: what test to use?

    Thanks a lot for your answer. The reason I decided to look at anxiety as a group, was because when using a cut-off score based on the literature I could find, this was the only way to get two groups that were roughly of the same size (n=16 & n=22). When using statistical rules (like >2SD's from...

    Multilevel analysis: Nesting variables to participants and comparing groups: what test to use?

    Thanks for the tip! I don't know how to move my post but I rewrote it partly and added it to the Psychology thread.

    I don't know how to report my results: did I use the wrong test?

    The aim of my thesis is to see whether anxiety score can predict sleep quality and dream content. So for this, there is one continuous variable (=anxiety score) that I want to use as a predictor on multiple dependent variables to see whether it can predict the outcomes on those variables. In...

    Multilevel analysis: Nesting variables to participants and comparing groups: what test to use?

    Oh, I’m so sorry. I confused the definitions of the independent and dependent variables. After three years of university and four courses on statistics, I still haven’t mastered the lexicon. I edited my post, hopefully it is more clear what I mean now. There is just one independent categorical...

    Multilevel analysis: Nesting variables to participants and comparing groups: what test to use?

    Hi all, Hopefully, somebody can help me. I've been struggling for two weeks now on how to analyze the data for my thesis. The design of the original study is as follows: 38 participants filled in multiple questionnaires and did a memory test in the evening. During the night, they were awoken...
