Note: For the two-way ANOVA, you will be expected to create a line graph as covered in
the SPSS tutorial in the Course Content (and not a boxplot as in the textbook). This applies
to future cumulative questions as well.
Green & Salkind: Lesson 26, Exercises 1, 4, 5, 6, 7, and 8
The following helpful tips are numbered to correspond with the exercise number to which they
refer (a dash indicates that no tips are needed):
1. Instead of identifying these values on your output, as the text states, please write
them into your Word file as written answers for #1 a, b, c, and d. (2 pts for output; a-d = 2
pts each)
4. Produce a line graph instead of a boxplot for this problem. Follow directions in
course SPSS tutorial for setting up a line graph. (2 pts)
5. -------------- (2 pts)
6. -------------- (2 pts)
7. All homework ―Results sections‖ should follow the example given in the Course
Content document ―Writing Results of Statistical Tests in APA Format‖ (note: you do not
have to refer to a figure). (2 pts)
8. Produce a line graph instead of a boxplot for this problem. Follow directions in
course SPSS tutorial for setting up a line graph. (2 pts)
Part Two:
1. A health psychologist is interested in the effects of exercise on stress in people
who regularly exercise. Specifically, she is interested in the type of exercise as well as the
time of day that the individual exercises. She recruits participants from a local health club
who regularly participate in one of three types of exercise: swimming, aerobics, and
tennis. She further divides these participants by whether they exercise in the morning or
the evening. She then administers a questionnaire to each individual assessing their self-
reported stress level. (HIGHER SCORE = HIGHER STRESS). Conduct a two-way
ANOVA to analyze these data. Use Tukey’s test in order to conduct any necessary
post hoc analyses if there are significant main effects. You do not have to follow up
on significant interactions at this time.
The steps will be the same as the ones you have been practicing in Part One of the
assignment—the only difference is that you are now responsible for creating the data file
as well. Remember to name and define your variables under the ―Variable View,‖ then
return to the ―Data View‖ to enter the data.
