1. ### MANCOVA with 2 dummy variables (Question about interaction probing)

Hello! I am running a MANCOVA with two dichotomous IVs and a 4 continuous DVs for my Master's thesis. When the first edits came back, I was asked to write about post-hoc probings of significant interactions. I am having a hard time understanding how one would "probe" these types of interaction...
2. ### The difference of means as a fulfilled precondition for a mediation analysis

The preconditions for a simple mediation analysis according to Hayes (2013) are statistically significant associations between X (the independent variable) and M (the mediator) as well as associations between M and Y (the dependent variable). In the case of a dichotomous independent variable...
3. ### presenting the results of logistic regression with dichotomous IVs

I have a question about how to present the results of a series of 6 logistic regressions in which I have the same 2 dichotomous/binary IVs. The problem I have is that I am not sure how to organize the results. I would like to see some examples of how others have organized similar analyses. I...

5. ### Simple effects for 3-way interaction

Hi, I'm doing a regression analysis with a continuous outcome variable (motivation), 2 continuous predictor variables (income and age), and 1 dichotomous predictor variable (condition). I have determined that there is a significant 3-way interaction, and that in both conditions, there are...
6. ### Skewed Continuous Predictor - dichotomize or treat as continuous?

Hello All, I have two scales with 7 binary items. The simple raw scores from these scales (summing the item responses of 0 or 1) are very skewed with about 56% of the sample having a scale score of 0. This is not unexpected as the scale measures behavioral problems with higher scale scores...
7. ### Mcnemar's test for dichotomous IV vs. dichotomous DV: how pertinent is it?

I intend to study the effect of a given psychological intervention (dichotomous independent variable) on the compliance of a medical treatment (dichotomous dependent variable). For this purpose, the compliance of a number of patients will be “measured” in two different moments (say M1 and M2)...
