Sobel Equation = A * B / √ ( B2 * Sa2 + A 2 * Sb2 )
Aroian Equation = A * B /√ ( B2 * Sa2 + A 2 * Sb2 + Sa2 * Sb2 )
A = Association between IV & mediator Coefficient.
B = Association between mediator & DV
Sa = Standard error of A.
Sb = Standard error of B.
IV = Independent Variable.
DV = Dependent Variable.
