Narrative: Case study 6.1 summary
The case study investigates whether mindfulness mediation can help college students perform better on exams.Forty-eight undergraduates were recruited and randomly assigned to either a meditation class or a nutrition class.For the two treatments, scores were measured on a verbal reasoning test both before the treatments and after the treatments.The test scores for the nutrition group showed no change, whereas the test scores for the meditation group improved from 460 before the treatment to 520 afterwards.This was a 16-percentile increase.

-{Case study 6.1 narrative} One of your classmates argues that test scores are expected to improve in sequential testing scenarios.The argument asserts that the first test serves somewhat as a "test preparation course" for the second test.If this is true, the study may say more about the negative effect of the nutrition class than it does about the positive effect of the meditation class.How can the experiment be redesigned to control for this lurking factor?
