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
