Enter the sum of the square of residuals and the total sum of squares into the calculator to determine the coefficient of determination.

Coefficient of Determination Formula

The following formula is used to calculate the R squared, or the coefficient of determination.

R2 = 1 – (RSS/TSS)

  • Where R2 is the coefficient of determination
  • RSS is the sum of squares of residuals
  • TSS is the total sum of squares


What is a coefficient of determination?

A coefficient of determination, also known as R squared, is a measure of the variation in one variable to another. In other words, it’s a measure of the correlation of data squared.
