Quizplus · Accepted Answer

The number of scores in a sample that are free to vary, or the number of independent pieces of information available in a sample, is referred to as degrees of freedom (df). It represents the number of scores that are allowed to vary once certain information is known, such as the sample mean or the sum of the scores. The formula to determine degrees of freedom is df = N - 1, where N is the sample size. Therefore, the correct choice is C, the degrees of freedom.
