Question

What would be the hypothesis for a mediation regression analysis? One predictor, one outcome and one mediator.

Answer 1

Mediational hypotheses are the kind of hypotheses in which it is assumed that the affect of an independent variable on a dependent variable is mediated by the process of a mediating variable and the independent variable may still affect the independent variable. In other words, in mediational hypothesis, the mediator variable is the intervening or the process variable. The mediational hypothesis assumes the complete mediation in the variables.

The term complete mediation in mediational hypothesis means that the independent variable does not at all affect the dependent variable after the mediator variable has controlled it. The mediation model involved in mediational hypothesis is a causal model.

The mediator variable in mediation hypothesis can be caused by the outcome variable. This happens when the initial variable is a manipulated variable—then it cannot be caused either by the mediator or the outcome in mediation hypothesis. However, since both the mediator and the outcome variables are not manipulated, they may cause each other in mediational hypothesis.

It is always sensible to swap the mediator variable and the outcome variable and have the outcome cause the mediator in mediational hypothesis.

Here,this is the appropriate answer of the given question above
