In a table listing the critical values of F, the degrees of freedom are listed as

a. degrees of freedom between and degrees of freedom within
b. degrees of freedom in the numerator and degrees of freedom in the denominator
c. degrees of freedom partial and degrees of freedom total
d. degrees of freedom of the rows and degrees of freedom of the columns

Question 2

When multiple values of F are given in a table, each for a corresponding value of alpha, which one should the experimenter report in order to behave in accordance with accepted practice? S/he should report the _____.

a. value that was set prior to data collection
b. highest value given (e.g., the one for = .10), as long as the obtained F is less than it
c. lowest value given (e.g., the one for = .001) as long as the obtained F is equal to or than greater than it.
d. a value exactly half way between the highest and lowest values of the critical F

Answer to Question 1

B
The degrees of freedom are listed as those in the numerator and denominator because different analyses of variance specify degrees of freedom with names other than between and within,but because F is a statistic that results from a ratio, there is always a numerator and a denominator associated with its calculation.

Answer to Question 2

C
It is accepted practice to report the significance of F at the lowest value at which F is still significant.
