Question

A repeated-measures study comparing four treatment conditions with a sample of n = 7 participants would produce an F-ratio with df = 3, 18.

True

False

Answer 1

SOLUTION:

From given data,

A repeated-measures study comparing four treatment conditions with a sample of n = 7 participants would produce an F-ratio with df = 3, 18.

sample size = n = 7

treatment conditions = k = 4

df = n-1 = 7-1 = 6

F-ratio with df = 3, 18 is correct answer,

Proof:

let us consider the formula,

[ k-1 , (k-1)*(n-1) ]

[ 4-1 , (4-1)*(7-1) ]

[ 3 , 3*6 ]

[ 3 , 18 ]

There fore, F-ratio with df = 3, 18 is correct answer then this is True
