Question

An experiment has a single factor with four groups and two values in each group. a. How many degrees of freedom are there in determining the among-group variation? b. How many degrees of freedom are there in determining the within-group variation? c. How many degrees of freedom are there in determining the total variation? a. There is/are degree(s) of freedom in determining the among-group variation. (Simplify your answer.) b. There is/are degree(s) of freedom in determining the within-group variation. (Simplify your answer.) c. There is/are degree(s) of freedom in determining the total variation. (Simplify your answer.)

Explanation / Answer

Solution:-
a. c-1 = 4-1 = 3
There is/are 3 degree(s) of freedom in determining the among-groug variation.

b. n-c = 8-4 = 4
There is/are 4 degree(s) of freedom in determining the within-group variation.

c. n-1 = 8-1 = 7
There is/are 7 degree(s) of freedom in determining the total variation.
