[answered] A repeated-measures experiment comparing only two treatment

A repeated-measures experiment comparing only two treatments can be evaluated with either a?t?statistic or an ANOVA. As we found with the independent-measures design, the?t?test and the ANOVA produce equivalent conclusions, and the two test statistics are related by the equation?F?=?t2.

The following data are from a repeated-measures study.

 Subject Treatment 1 Treatment 2 Difference 1? 1 9 +8 2? 2 3 +1 3? 2 4 +2 4? 1 7 +6

(a) Use a repeated-measures?t?statistic with???= 0.05 to determine whether the data provide evidence of a significant difference between the two treatments. (Caution:?ANOVA calculations are done with the?X?values, but for?t?you use the difference scores. Round your answers to three decimal places.)?

 t-critical =? ? t?=?

Conclusion??

Fail to reject the null hypothesis. There are significant differences between the two treatments.Reject the null hypothesis.

(b) Use a repeated-measures ANOVA with???= 0.05 to evaluate the data. (You should find?F?=?t2.) Fill in the missing values. (Round your answers for?SS,?MS, and?F?to two decimal places.)?
