an anova procedure is used for data that were obtained from five sample groups each comprised of six observations. the degrees of freedom for the critical value of f are . a. 5 and 26 b. 4 and 29 c. 4 and 25 d. 4 and 30

The number of separate bits of information required to construct a statistic is called the degrees of freedom, which is frequently denoted by the letters v or df.
It is determined by subtracting the number of constraints from the sample size.
The greatest number of logical manner independent variables is, values with the freedom to change—in the data sample is referred to as the degree of freedom.

The essential value F's degrees of freedom are (k-1,n-k).

Four sample groups are provided to us, so,

k = 5.

Additionally, we know that each of the five groups has six observations, therefore

n = 5*6

n = 30

The crucial factor F can vary in freedom.

(k-1,n-k)

(5-1, 30 - 5)

(4,25).

Its degrees of freedom again for critical F value are as a result (4,25).
