nswered out of 1.00 question An experiment to determine the most effective way to teach safety principles applied four different teaching methods. Some employees were given programmed instruction booklets and worked through the course at their own pace. Other employees attended lectures. A third group watched a television presentation, and a fourth group was divided into small discussion groups. A high of 10 was possible. A sample of five tests was selected from each group. The test grade results were: Programmed Instruction Lecture TV Group Discussion 5 6 6 8 The degrees of freedom in the numerator and denominator of the F statistics for treatments respectively are: Select one: a, 3, 15 b.4, 20 ?. 4, 16 d. 3, 16 e. 3,19Explanation / Answer
Given :-
The degree of freedom in the numerator and denominator of the F statistic for treatment is,
Answer :-. Option "d" is correct. (3,16)
Explain-
Number of groups (K) = 4
Total values (n) = 20
We have to use numerator = df Between treatment and denominator = df within treatment
df = degree of freedom.
df of Between = k-1 = 4-1 = 3
df total = n-1 = 20-1 = 19
And
df of within = 19-3 = 16
