The most general rule that governs degrees of freedom is that A) df = N-1 B) df = $\Sigma$(X - $\bar { X }$ )² C) degrees of freedom depend on the $\alpha$level D) degrees of freedom depend on the number of observations minus the number of parameters estimated with statistics.

Question

Quizplus · Accepted Answer

Degrees of freedom generally refer to the number of values in the final calculation of a statistic that are free to vary. This is typically conceptualized as the number of observations minus the number of parameters estimated, which allows for the calculation of various statistical properties, such as variances and t-tests, under the constraint of the sample data.
