Aresearcher reports an f-ratio with df = 2, 18 from an independent-measures research study. based on the df values, how many treatments were compared in the study and what was the total number of subjects participating in the study?

3 treatments and 21 subjects were participating in the study .

Step-by-step explanation:

Let the number of treatments be k and the total number of subjects participating in the study be n.

Then , the df for numerator of F-ratio = k-1

df for denominator of F-ratio = n-k

Given : A researcher reports an F-ratio with df = 2, 18 from an independent-measures research study.

Based on the df values, we have

k-1 = 2 and n-k= 18

If

Then,

Therefore , 3 treatments were compared in the study and 21 subjects were participating in the study is 21.

14.3

step-by-step explanation:

add all the numbers together.

9 + 12 + 15 + 16 + 17 + 17 = 86

now, divide 86 by how many numbers we have: 6.

86 / 6 = 14.3

well we know there are 4 clubs in 52 cards so it’s replaced so it should be 3/51
