For which of the following situations would a repeated measures research design be appropriate?
* comparing verbal solving skills for science majors vs art measures
* comparing math skills for girls vs boys at age 10
* comparing pain tolerance with and without acupuncture needles ( i chose this one)
* comparing self esteem for students who participate in school athletics vs those who don't.

A repeated measures study uses a a total of n=10 participants to compare 2 treatment conditions. how many scores are measured in this study, how many scores are actually used to compute the sample mean and sample variance?
* 20 measured and 20 used
* 10 measured and 10 used
* 10 measured and 20 used
* 20 measured and 10 used ( i chose this one)

The following data were obtained from a repeated measures study. What is the value of MS for these data?
Subject 1st 2nd
#1 10 15
#2 4 8
#3 7 5
#4 6 11

*3.5 ( i chose this one???)
*4
*3
* 4.5

The following data where obtained from a repeated measures study. what is the value of SS for the difference scores?
Subject 1st 2nd
#1 10 11
#2 4 6
#3 7 9
#4 6 5

*1 (this is the one i had chosen??)
*6
*4
*10

A repeated measures study using a sample of n=20 participants would produce a t statistic with df=_____.
* 20
* 39
*9
*19

A research study produces a t statistic with df=14. for this study which of the following designs would require a total of 30 participants?
* none of these choices
* an independent measures design ( i chose this one)
* a repeated measures design
* a matched subjects design

A repeated measures study and an independent measures study both produces a t statistic with a df=10. how many individuals participated in each study?
* 11 for repeated measures and 11 for independent ( i chose this one?)
* 11 for repeated and 12 for independent
* 12 for repeated and 12 for in independent
* 12 for repeated and 11 for independent

For the repeated measure t statistic , df=______.
* n1+n2-2
* (n1-1)+(n2-1)
* n1 +n2-1
*n-1 (this is the one i chose?)

Which of the following is the correct null hypothesis for a repeated measures t test?
* uD=0
*M1-M2
*MD=0
*u1=u2

If the null hypothesis is true, what value is expected on average for the repeated measures t statistic ?
* 1
*0 ( i chose this one)
*t>1.96
* 1.96

## Proper usage of the one-way, repeated measures, and factorial ANOVA

Find three research studies of interest to you that provide proper usage of the one-way, repeated measures, and factorial ANOVA.

State the null hypothesis that was tested in each study. Interpret the F statistic for each study and make a determination regarding the null hypothesis (reject or fail to reject). Comment further on interaction or main effects when appropriate.

Lastly, why do researchers utilize an ANOVA of the t-test? Find a set of data that is suitable for an ANOVA and perform both the appropriate ANOVA and the appropriate t-test on the data.

Comment on your statistical findings? Do you agree with your initial statement regarding the preference of an ANOVA over a t-test when examining more than two groups?
