I want to explore whether attitudes mediate the relationship between employment status and intention to apply to graduate school. (See image below).
I planned to use the Sobel Test to explore the mediation, but I'm not sure I can. How does one/how can one test for mediation with a categorical predictor and both a continuous mediator variable and dependent variable? Prefer answers oriented to SPSS.
