## [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 2 3 +1 2 2 3 +1 3 1 5 +4 4 2 3 +1

(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 = ? 1
