Detailed explanation-1: -Degrees of freedom, often represented by v or df, is the number of independent pieces of information used to calculate a statistic. It’s calculated as the sample size minus the number of restrictions.
Detailed explanation-2: -Degrees of Freedom Formula Some calculations of degrees of freedom with multiple number of parameters or relationships use the formula Df = N-P, where P is the number of different parameters or relationships. For example, in a 2-sample t-test, N-2 is used because there are two parameters to estimate.
Detailed explanation-3: -First multiply the critical value by the standard deviation. Then divide this result by the error from Step 1. Now square this result. This result is the sample size.
Detailed explanation-4: -If we know that the mean of this sample data is 20, but do not know the values of any of the data, then there are 99 degrees of freedom. All values must add up to a total of 20 x 100 = 2000.
