For this question, you have to do two analyses. Using Chapter 13 Data Set 5 (ch13ds5.csv), compute the t score for the difference between two groups on the test variable (named score). Then, use Chapter 13 Data Set 6 (ch13ds6.csv) and do the same. Notice that there is a difference between the two t values, even though the mean scores for each group are the same. What is the source of this difference, and why—with the same sample size—did the t values differ?
