Dr. Webkamigad has developed a new logical reasoning test. She administers the test to a group of incoming freshman. The next year, she tests the same students, who are now sophomores, and finds that the overall correlation between the two sets of scores is -0.25. What should Dr. Webkamigad conclude about her new test, based on this information?
