ANOVA

You are currently doing research on the effects of school and work on stress. As such,

you have divided young adults into those who both work and attend college, those who only attend college, and those who only work. You think that these three groups of

young adults all experience different levels of stress. So you collect information on the level of stress (on a scale of 1 (least stress) to 20 (most stress)) experienced by 15 young adults (5 individual in each of the three categories). The stress scores for these adults are as follows:

Work and School - School Only - Work Only

15.0 10.8 8.6

19.2 13.6 10.4

8.4 6.2 6.4

12.8 7.4 5.6

10.2 9.8 6.6

Perform the appropriate hypothesis test, at alpha = .05, to determine whether there is a

relationship between school/work with stress. Be sure that you include all of the steps

(including stating your research and null hypotheses) and show any calculations you perform.

Do you reject or fail to reject the null hypothesis?

What does this decision mean? (i.e. following your decision, state your conclusions in a complete sentence)?

What is the strength of this relationship

(hint: calculate eta-squared)?

Is this a weak, moderate or strong relationship?

(NOTE: The SS between is 79.32 and the SS within is 120.53)
