1.A benefit of the related measures design is

a.it gets rid of the individual differences confound

b.both answers are correct

c.it may require a smaller sample,and thus be easier to conduct.

2.The null hypothesis for the related samples T test is

a.Mew D =0,or, there is no difference in the two sets of scores.

b.The sample mean difference is equal to zero

c.The standard error is zero

d.Mew D is not equal to zero

3.The sample size is 16,and the SD of the difference scores is 3.What is the standard error for this data?

a..5

b.there is no way to calculate this answer

c.3/16

d.3/4 or .75

4.the formula for the dffor the repeated measures t test is

a.n-2

b.(n1-1)+(n2-1)

c.n-1,where n is the number of pair of scores

d.n+1

5.I conduct a related samples T test and find that my p value is .10.this means

a.my test statistic did not make it into the critical region, and I can't reject the null

b.there is a 10% chance my data are in the null distribution

c.all the answers are correct

d.it is possible I am making a type two error

6.The numerator for the related samples T test is

a.the standard error

b.M1-M2

c.the difference scores

d.The mean of the difference scores
