Degrees of Freedom Calculator

Enter the total number of samples of a data set into the calculator. The calculator will display the total number of degrees of freedom. The calculator will also display the t-statistic if the additional information needed is displayed.

Degree of Freedom Formula

The following formula is used to calculate the degrees of freedom.

DOF = N – 1

  • Where DOF is the degrees of freedom
  • N is the sample size

How to calculate degrees of freedom

  1. First, determine the sample size

    Calculate of measure the total size of the sample.

  2. Calculate the DOF

    Calculate degrees of freedom by subtracting 1 from the sample size determined in step 1.


What is degrees of freedom?

Degrees of freedom are a measure of the total number of independent pieces of information that go into any statistical information based on a sample size.
