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.
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.
