Create a Line Graph as Covered in the SPSS Tutorial

Part One:

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. (2 pts for output, – 1 pt if no post hoc)

Morning	Swimming	Aerobics	Tennis
10 16 12 16 9	19 21 16 18	17 21 18 14
Evening	14 13 8 12 12	17 12 14 9 10	12 15 19 14

2. 
Write an APA-style results section describing the
outcome. 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). For the two-way ANOVA, be sure to
include statistical statements concerning the F ratios and p values for both
main effects and the interaction, and interpretation statements about all 3 of
these effects. (2 pts)

3. 
Is there a significant interaction effect? (2 pts)

4. 
Based on your results, is there one type of exercise
that seems more effective in reducing stress than the others? Remember that
higher scores = higher stress. (2 pts)

This assignment is due by 11:59 p.m. (ET) on Monday of
Module/Week 4.

Part Three:  Cumulative Homework

1.  An investigator in child development research
is studying the development of object permanence – the understanding that an
object still exists even if its out of sight. She tests three groups of infants
– ten who are 9 months old, 8 who are 12 months old, and 10 who are 15 months
old. She presents each of the infants with 10 trials. On each trial, a toy is
first shown to the child and then covered with a piece of cloth. The infant
demonstrates object permanence if he or she looks for the object when it’s
covered. Each infant is given a score for the number of trials (out of 10) on
which he or she shows object permanence. Is there a significant difference
between the groups on demonstrations of object permanence? Choose the correct
test to analyze this question, set up the SPSS file, and run the analysis.
Follow the directions under the table below.

9 Months	8, 3, 4, 6, 5, 4, 9, 2, 0, 1
12 Months	10, 5, 6, 7, 6, 5, 10, 3
15 Months	10, 8, 9, 9, 8, 7, 9, 6, 6, 8

a) 
Paste appropriate SPSS output. (2 pts)

b) 
Paste appropriate SPSS graph. (2 pts)

c) 
Write an APA-style results section describing the
outcome. 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)

2. 
A researcher wanted to investigate whether there was a
difference in satisfaction ratings in an assisted living facility between
residents who had a pet with them vs. those who did not have a pet.  She administered a scale asking them to rate
their overall satisfaction with the facility. 
Did having a pet have an impact on the residents’ overall satisfaction
levels? Choose the correct test to analyze this question, set up the SPSS file,
and run the analysis. Follow the directions under the table below (on next
page).

Pet	47 42 35 46 49 39 40 46 52 40
No Pet	30 25 24 42 28 25

a) 
Paste appropriate SPSS output. (2 pts)

b) 
Paste appropriate SPSS graph. (2 pts)

c) 
Write an APA-style results section describing the
outcome. 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)
