    Interaction effect but no simple effects?

    Hi All, I have conducted a two-way within-subject repeated measures ANOVA, examining a dependent variable over 5 time-points under 2 conditions. An interaction effect is revealed but when I proceed to examine the simple effects using one-way ANOVAs there are no significant effects. I am not a...

    F test significant but simple contrasts not

    Thank you both for your input. I conducted post-hoc analyses just to see if there was a difference elsewhere (i am not interested in this) but it did flag a difference between level 2 and level 3 so I think that may be why. Excuse my naivety here but I am wondering why there is an F statistic...

    F test significant but simple contrasts not

    Hi All, I have conducted a repeated measures ANOVA, examining one of my dependent variables over 5 time points. I have a significant main effect from my F test but not when i am examining my simple contrasts (see images below). Could anyone offer any advice on why this is and what should be...

    Post-hoc pairwise or simple contrast ANOVA

    Hi All, I am examining a dependent variable over 5-time points but what I am really interested in is how the dependent variable differs in comparison to the first time-point (baseline). Firstly, which ANOVA is more appropriate, a repeated measures ANOVA with post-hoc analyses or a simple...

    Multiple imputation SPSS

    Hi All, I have been reading up on how to conduct multiple imputation on SPSS but wondered if there are any general ruled of thumb or references available to advise on how many iterations and imputations to use? Thank you in advance.

    SPSS insufficient memory Fisher exact test

    There are greater than 20% of responses with fewer than 5 responses so I have avoided chi-squared test in this instance. The sample size is 405.

    SPSS insufficient memory Fisher exact test

    Hi All, I have been conducted analyses on a study using the Fisher Exact test but have currently encountered an issue with my larger contingency tables (3x7 and 3x9) as SPSS has insufficient memory to conduct the analyses. In this scenario it is best to use a Monte Carlo simulation on these...

    ANOVA with missing case

    Thank you for your response. Would I be correct in thinking that this is a random effects model and the subject ID is entered as the random variable?

    ANOVA with missing case

    Hi All, I was wondering if anyone could shed some light on a current situation I have encountered. I have a study set-up with 13 participants that I am examining over 5 time-points, hence, I intend to conduct a one-way ANOVA. However, on one of the time-points, a participant was unable to...

    Non-parametric Two-way ANOVA

    I tested the residuals and they were still non-parametric, i was thinking of conducting Friedman's tests for within analyses and Kruskal-Wallis tests for between analyses.

    Non-parametric Two-way ANOVA

    My data are non-normally distributed to better describe the situation. I would like to know whether there is an effect over time (within analysis), so I was presuming I would use a Friedman test. I would also like to know whether there were any differences between the training groups at any...
