19. A repeated-measures study comparing two treatments with a sample of n 10 participants produces a mean of M 8 for the scores in the first treatment, a mean of M 10 for the scores in the second treatment, and a mean of MD 2 with Sum of squares of the difference SS 64 for the difference scores. What is the estimated standard error for the sample mean difference? Answer:

For either independent-measures or repeated-measures designs comparing two treatments, the mean difference can be evaluated with either at test or an ANOVA. The two tests are related by the equation F=12. The following data are from a repeated-measures study: Person Difference Scores 3 I 4 2 3 7 M = 4.00 T = 16 SS = 14 Treatment II 7 11 6 10 M 8.50 T-34 SS = 17 3 3 Mo 4.50 SS = 27.00 Use a repeated-measures t...

4. Calculating the standard deviation and the estimated standard error for the sample mean difference Aa Aa A researcher is interested in hamster wheel-running activity during the summer versus the winter. He suspects that either the hamsters will run less during the winter to conserve energy or they will run more to keep warm. He records the activity of n = 16 hamsters during June, July, and August and compares their running-wheel revolutions per hour to the activity of the...

differences can substantially enefit only occurs if the Pla We 6:00 reduce variance and lower the standard error. However, thi individual differences are consistent across treatment conditions. In problem 21, for example, the particlpants with the highest scores in the more-sleep condition also had the Mini Wec 6:00 sche apol inco highest scores in the less-sleep condition. Similarly, participants with the the first condition also had the lowest scores in the second condition. To construct the st scores in following...
