30 sec • 1 pt
This test is used to compare the responses to a treatment in a within-groups design (ie, does an SAT prep course improve an individual’s SAT scores?). A listening test was administered to Spanish teachers before and after an institute designed to improve Spanish listening skills. The maximum possible score on the test was 36. The Pre- and Post-test results for each subject are listed below:
Sub 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19
Pre 30 28 31 26 20 30 34 15 28 20 30 29 31 29 34 20 26 25 31
Pos 29 30 32 30 16 25 31 18 33 25 32 28 34 32 32 27 28 29 32
Determine if the institute improved listening skills at the 5% significance level.
