Detailed explanation-1: -You end up with n-1 degrees of freedom, where n is the sample size. Another way to say this is that the number of degrees of freedom equals the number of “observations” minus the number of required relations among the observations (e.g., the number of parameter estimates).
Detailed explanation-2: -The degrees of freedom are n-2.
Detailed explanation-3: -Degrees of freedom is always the number of units within a given set minus 1. It is always minus one because, if there are parameters placed on the data set, the last data item must be very specific to make sure all other points conform to that outcome.
Detailed explanation-4: -Determine the size of your sample (N). Subtract 1. The result is the number of degrees of freedom. 13-Feb-2023
