Problem Set 3: One-Way randomized ANOVA

Research Scenario: A health psychologist is looking into theeffects of different kinds of exercise on stress. She dividesvolunteers into three exercise groups: high-intensity intervaltraining (HIIT) (n=8), yoga (n=8), or running (n=8). The volunteersparticipate in a set number of hours of the exercise for a month,after which the psychologist measures their stress levels on ascale of 1-40 where lower scores = lower stress, and higher scores= higher stress. The scores for each group are shown in the tablebelow. Input the data into SPSS (remember you will enter the dataonly using 2 columns - one for group (make sure you label thevalues) and one fore stress. Conduct a one-way ANOVA to determinethe effect of these different exercises on stress levels.

HIIT	16	25	19	11	17	11	15	27
YOGA	19	21	22	23	14	24	27	15
RUNNING	19	28	33	24	26	30	17	21

11) Paste relevant SPSS output

12) Create an appropriate graph to display this data.

13) Write an APA-style Results section based on your analysis.All homework \"Results sections\" should follow the examples providedin the presentations and textbooks. They should include thestatistical statement within a complete sentence that mentions thetype of test conducted, whether the test was significant, and ifrelevant, effect size and/or post hoc analyses. Don't forget toinclude a decision about the null hypothesis.
