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

**First, determine the sample size**Calculate of measure the total size of the sample.

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