I'm quite new to this topic, so this is probably very basic for most of you:
I want to analyse the relationship of multiple variables via partial correlation as an alternative for a regression analysis. I don't only want to find out how the independent variables relate to the dependent variable but also I want to analyse the relationship between the ivs.
I have one dichotomous dv and eight ivs that are both qualitative and quantitative. Is it possible to run a partial correlation analysis though the variables have different scales? Is there something I need to consider? For example: do I have to test two-tailed or one-tailed? Do I have to run bivariate correlation/chi square tests too?
