Indirect Effect Calculator for Mediation Models

Indirect Effect Calculator for Mediation Models

Calculate the indirect effect using the product-of-coefficients method: $$ \text{Indirect Effect} = a \times b $$

* Enter the path coefficient \( a \) (from the independent variable to the mediator) and \( b \) (from the mediator to the dependent variable).

Step 1: Enter Parameters

Path Coefficient \( a \) (IV → Mediator):

e.g., 0.5

Path Coefficient \( b \) (Mediator → DV):

e.g., 0.4
