# 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?

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.
