  Sobel Test Calculator for the Significance of Mediation

This calculator uses the Sobel test to tell you whether a mediator variable significantly carries the influence of an independent variable to a dependent variable; i.e., whether the indirect effect of the independent variable on the dependent variable through the mediator variable is significant. This calculator returns both the one-tailed and two-tailed probability values.

Please supply the necessary parameters, and then click the 'Calculate' button.

A: The regression weight (regression coefficient) for the relationship between the independent variable and the mediator.
SEA: The standard error of the relationship between the independent variable and the mediator.
B: The regression weight (regression coefficient) for the relationship between the mediator variable and the dependent variable.
SEB: The standard error of the relationship between the mediator variable and the dependent variable.
