In inferential statistics, you estimate a parameter of a population by calculating a statistic of a sample. The number of independent pieces of information used to calculate the statistic is called the degrees of freedom. The degrees of freedom of a statistic depend on the sample size: 1. When the sample size is … See more The degrees of freedom of a test statistic determines the critical value of the hypothesis test. The critical value is calculated from the … See more The degrees of freedom of a statistic is the sample size minus the number of restrictions.
