To use the Distributions tool to find the critical values, you first need to set the degrees of freedom in the tool. The degrees of freedom are The critical values (the values fort scores that separate the tails from the main body of the distribution, forming the critical region) are Finally, since the t statistic v in the critical region, you v the null hypothesis.

Consider the following data from a repeated-measures design. You want to use a repeated-measures t test to test the null hypothesis Ho: Pp = 0 (the null hypothesis states that the mean difference for the general population is zero). The data consist of five observations, each with two measurements, A and B, taken before and after a treatment. Assume the population of the differences in these measurements are normally distributed. Complete the following table by calculating the differences and the squared differences: Difference Score Squared Difference Score Observation A B (D = B - A) (D:) 1 1 2 2 3 3 6 5 5 6 The mean difference score is Mp = v, For a repeated-measures t test, you need to calculate the t statistic, which requires you to calculate s and sMD. What is the estimated standard deviation of the difference scores? 6.80 / What is the estimated standard error of the mean difference scores? (Note: For best results, retain at least six decimal places from your calculation of s.) SMD s/ What is the t statistic for the repeated-measures t test to test the null hypothesis Ho: Pp = 0?
