The number of scores that can vary in the calculation of a statistic is called ______.
A) the degrees of freedom
B) homogeneity of variance
C) multivalent variable
D) the null hypothesis

Question

Quizplus · Accepted Answer

Degrees of freedom is the number of scores that can vary in the calculation of a statistic while holding the sample size constant. It is an important concept in statistical hypothesis testing and is used to determine the critical value of a test statistic. Homogeneity of variance refers to the assumption that the variance of the population is equal across all groups or conditions being compared. Multivalent variable is not a statistical term. The null hypothesis is a statement that there is no significant difference between a set of observed data and a hypothesized population parameter. While it may be related to the concept of degrees of freedom, it is not a direct answer to the given question.
