To test this Professor Jacobs set up the following conditions surrounding his next lecture. He randomly assigned his 15 Psych B5 students into three different groups of 5. Each group viewed a one-hour lecture on independent one-way ANOVAs. One group was instructed to study for the following two-hours (cram group). One group was told to go rest and relax (rest group) for the next two-hours. A third group (control group) wasn't given any instruction at all. The students were all brought back into the classroom. Professor Jacobs conducted a 15-minute review session and then administered a 10-point quiz. Conduct an independent one-way ANOVA to determine if resting did improve scores.
