Degree of freedom and critical value
WebAug 8, 2024 · Degree of freedom (df) = the sample size - 1. This means that the number of samples you have in your study subtracted by one will equal the degree of freedom. So if you have a sample size of 25, subtract one from this value to get the degree of freedom. In this case, it would be 24. 4.
