Question 1193826: A portion of an ANOVA summary table is shown below.
Source Sum of Squares Degrees of Freedom
Between 19 3
Within (error) 34 26
Total 53
The critical value for this problem should have dfN (degrees of freedom in the numerator) and dfD (degrees of freedom in the denominator) of
A. dfN = 3, dfD = 26
B.dfN = 19, dfD = 34
C. dfN = 34, dfD = 19

You can put this solution on YOUR website! **In ANOVA:**
* **dfN (degrees of freedom numerator)** refers to the degrees of freedom associated with the **between-groups** variation.
* **dfD (degrees of freedom denominator)** refers to the degrees of freedom associated with the **within-groups** (error) variation.
**From the given ANOVA table:**
* **Between-groups degrees of freedom (dfN): 3**
* **Within-groups (error) degrees of freedom (dfD): 26**
**Therefore, the correct answer is:**
**A. dfN = 3, dfD = 26**
