    Can you help me decide if there is statistical significance here?

    Hi, I've attached a word file - it contains exam results. There were two sessions - one AM and one PM. . I am trying to work out if there is a statistical significance between the achievement of the AM and PM groups and whether moderation should have occurred here? Can anyone help? I have...

    Is here a moderation (when b coefficients are nonsignificant)?

    I am trying to check if the relationship between X and Y is a moderated by M. Model is: Y = X + XX + M + XM + XXM X - independable, M - moderator, Y - dependable. Variables are continuous and normal. First I multiply, then center the variables (I hope it is right). Then run reggresion...

    Logit regression interaction/moderation: what to do about it?

    Hi all! I have a multivariable logit regression model that has two terms showing two-way interaction (the interaction also makes biological sense.) So what am I to do about it? Do I just mention it in my findings? Do I remove one of the variables? (How do I decide which one?) I...

    Do i need to correct for family wise error when doing moderation and mediation?

    Hi, I've been analyzing data for moderating and mediating relationships and am wondering how necessary it is to correct for family wise error in moderation and mediation analysis. I have read arguments for and against correction for family wise error in the literature. My moderation/mediation...

    Interaction or moderation effect - suitable method for analysis?

    I have run a two-way between groups ANOVA to analyse my data. However, I have one more variable, which is not one of the factors in the ANOVA. I want to see how this variable interacts with one of the factors. I predicted that it will be a moderator. This variable is measured based on scores...
