Effect Size Calculator for Multiple Regression

Effect size is a statistical concept that performs the quantitative measure of the strength of a relationship between two variable. It is also used to measure the regression coefficient in a multiple regression. Use our online Effect size calculator for multiple regression for calculating effect size for multiple regression based on the value of observed squared multiple correlations (R2). Multiple regression effect size calculator is designed in a user-friendly manner.

Formula:

F² = R² / (1 - R²) Where, F² = Effect Size R² = Squared Multiple Correlation

Example:

Calculate the effect size for multiple regression with the observed squared multiple correlation(R²) of 0.8.

Solution:

F² = 0.8 / (1 - 0.8)
= 4
