In this case, there was a problem during data collection. After the post-tests were collected, the researcher realized that the post-test form did not ask for the students' I.D. numbers. So, it will be impossible to match pre-test scores to post-test scores. To salvage the project, the researcher realizes he has 40 pre-test scores and 40 post-test scores but no way to link them. The researcher realizes that he can still compare pre-test vs. post-test scores by using a between-subject design rather than a within-subjects design.
Using the attached file, please create a new dataset that can be used with the between subject design. You will no longer need the variables CreativePre and CreativePost Test. Instead, you will have only one variable for the score on the creativity test. A second (or grouping variable) will serve to indicate which test the student took. Give the new file a name. Also, show all work.
