Unlike normal mediation analysis you don't have to show the IVpredicts the DV in Block 1 but you still need to show the IV predicts the suppressor and there is a sig indirect effect of IV -> DV via the suppressor. I have a binary DV, a binary IV, and groups of mediators that consist of categorical, continuous, and dichotomous variables. The statistical significance of the indirect effect should be tested using bootstrapping (see Hayes [2013], Introduction to mediation, moderation, and conditional process analysis ). Moderation analysis in the behavioral sciences involves the use of linear multiple regression analysis or causal modelling. This is an example of a one-tail t-test as opposed to a two-tailed t-test outlined above.

Articles are more often focusing on explaining mediation analysis conceptually rather than mathematically. A wonderful example of this combination is the research by Correll et al on the motherhood penalty, which combined a field experiment about hiring and a lab experiment, which enabled a statistical mediation analysis. We will first create two regression models, one looking at the effect of our IVs (time spent in grad school, time spent with Alex, and their interaction) on our mediator (number of publications), and one looking at the effect of our IVs and mediator on our DV (number of job offers).
