The number of observations minus the number of constraints or assumptions needed to calculate a statistical term is called:
A)statistical power
B)t-level
C)degrees of freedom
D)significance level

Question

Quizplus · Accepted Answer

The number of degrees of freedom is defined as the number of observations minus the number of constraints or assumptions needed to calculate a statistical term. This concept is important in determining the appropriate critical values and probabilities to use in hypothesis testing and confidence interval calculations. Statistical power refers to the likelihood of detecting a true effect, t-level refers to the level of significance chosen for a hypothesis test, and significance level refers to the probability of rejecting the null hypothesis when it is true.
