The question was: What is the uncorrected t-value for the t-test on post-treatment scores?
Your Answer: -5.70
Answer and explanation: Your answer is incorrect. The correct answer is -5.26.
The uncorrected t-value is the one where it is assumed that the groups have equal variances. This is
uncorrected because this may not be true. The uncorrected t-value for the post-treatment scores is
-5.26. -5.70 is the corrected t-value for the post-treatment scores.
