Indirect Effect Calculator for Mediation Models

Indirect Effect Calculator for Mediation Models

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

* 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
