Consider the Data Table Shown with Values for Five Individuals

Multiple Choice

Consider the data table shown with values for five individuals measured in each of four groups (A, B, C, and D) . We will conduct an ANOVA analysis of this.
​
$\begin{array}{c}\text { Groups }\\\begin{array}{rrrr}\text { A } & \text { B } & \text { C } & \text { D } \\6 & 7 & 9 & 11 \\8 & 10 & 11 & 14 \\10 & 11 & 12 & 15 \\12 & 12 & 13 & 16 \\14 & 15 & 15 & 19\end{array}\end{array}$ ​
-To test the significance of the F-ratio value, what degrees of freedom would we use?

A) df = 3 in the numerator, df = 12 in the denominator
B) df = 3 in the numerator, df = 16 in the denominator
C) df = 4 in the numerator, df = 12 in the denominator
D) df = 4 in the numerator, df = 16 in the denominator
