1. If a set of n= 9 difference scores has a mean of MD= 3.5 and a variance of s2

Question

1. If a set of n= 9 difference scores has a mean of MD= 3.5 and a variance of s2 = 36, then the sample will produce a repeated- measures t statistic of t=3.5/2

True or False

2. In general, as the variance of the difference scores increases, the likelihood of finding a significant difference also increases.

True or False

3. Repeated- measures designs are particularly well-suited to research questions concerning the difference between two distinct populations

True or false

4. In analysis of variance produces SS between =40 and MS between = 20. In this analysis, how many treatment conditions are being compared .

A 20

B 4

C 3

D 2

5 For an independent- measures experiment comparing two treatment conditions with a sample of n= 10 in each treatment which of the following identified the correct df for the F-ratio?

A 1,19

B 1,18

C 2,19

D2, 18

Explanation / Answer

1)here std error =(s2/n)1/2 =2

hence test stat =3.5/2

true

2) false as variance increases likelihood of finding significant differnce decreases

3)false

4)as degree of freedom =SS/MS =2

hence treatments =df+! =3

5)B 1,18
