EXSC 520 Statistical Analysis in Exercise Science Case Study

EXSC 520CASE STUDY ASSIGNMENT INSTRUCTIONS
OVERVIEW
For each Case Study Assignment, use the SPSS demonstration indicated below. Each
demonstration will guide you through the following analyses and tests: assumptions testing,
statistical analysis, as needed post hoc analysis, and creation of tables and figures as needed.
Additionally, use the corresponding data and Case Study Template form to create and record
your findings as you interpret from the analyses.

CORRELATION AND BIVARIATE REGRESSION
T-TEST COMPARING MEANS FROM TWO SETS OF DATA
SIMPLE ANALYSIS OF VARIANCE
ANALYSIS OF VARIANCE WITH REPEATED MEASURES
FACTORIAL ANALYSIS OF VARIANCE
NONPARAMETRIC STATISTICS
To successfully complete each Case Study Assignment, all of the following instructions must
be adhered to along with meeting all the components of the Case Study Grading Rubric. Only
paste tables/figures in their designated location in the Case Study Template. Responses to
questions along with the Write-up must be written in paragraph format. Content should be
written in past tense as it conforms more to research journal format. When discussing statistical
significance, the specific p-value must be included (example: “heart rate was statistically greater
during running versus cycling (189 vs. 143 bpm) (p=0.03) as indicated in Table 1.”)

CASE STUDY: NONPARAMETRIC STATISTICS TEMPLATE
Instructions: To successfully complete this case study, all of the following instructions must be
adhered to. Only paste tables/figures that contain pertinent information. Only paste tables/
figures where you are instructed to do so. HIGHLIGHT (in yellow) only relevant the data from
tables; as well as your response to each question. In the write-up section, all information must be
provided in paragraph format. When statistical values are discussed, the numerical value must be
given and a reference must be made to the table(s)/figure(s) where the value(s) can be found. An
example of this is “heart rate was statistically greater during running versus cycling (189 vs. 143
bpm) as indicated in Table 1.
I.
Mann-Whitney- U
Research question: “Did the temperature of the environment cause the group’s core
temperature to be ranked significantly different (smallest number = coldest core
temperature ranking, largest number = hottest core temperature ranking)?”

II.
Kruskal Wallis
Research question: “Is there a statistical difference between the rankings of the core
temperatures of the groups exposed to either a cold, neutral, or hot environment (smaller
number= coldest core temperature ranking, largest number= hottest core temperature
ranking)?” Ranks that are tied, get an average value of the two ranks.

III.
Friedman’s Test
Research question: “Which conditions (no music, slow music or upbeat music) were more favorable
to participants while running on a treadmill? Smallest number= most favorable, largest number=
least favorable.

Write-up Mann-Whitney U
Write-up- Use these questions as a guide to write an abstract (paragraph). Use past tense.
The write-up must include the following. Use these questions as a guide.
1. What is the research question?
2. What is the mean and standard deviation for each group?
3. What is the MEAN RANK for EACH group?
4. What is the Mann-Whitney U value?
5. Was the analysis significant? How do you know? What was the sig value?
6. What do the statistical findings of these data suggest about the research question?

7. What are your thoughts on the finding of this analysis, and what are the practical
application(s) of this finding? Elaborate on what the study means, why, how you know,
and relate the findings to exercise physiology knowledge. Use references if needed.
(Hint- does this study “make sense?” What could influence results?)
