This document provides instructions for an assignment analyzing a repeated measures experimental design using SPSS. Students are asked to: 1) Perform exploratory data analysis and write a brief summary of an existing dataset containing test scores over 12 weeks. 2) Conduct a repeated measures ANOVA to analyze effects of time and gender on test scores. 3) Propose a hypothetical repeated measures study and identify variables and factors that could be analyzed using repeated measures ANOVA.

1. BTM8107-8 Week: 6 Activity: Apply Repeated-Measures A+ Solution
Activity Description
You will submitone Word documentfor this activity. You will create this Word documentby cutting and pasting SPSS
output into Word.
This assignmentconsists oftwo parts.In the firstpart, you will utilize an existing datasetto analyze the datasetfrom
repeated-measures experimental design.All SPSS outputshould be pasted into your Word document.In the second
part, you will be asked to create a datasetfor a hypothetical repeated-measures experimental design.Finally,you will
answer questions aboutyour hypothetical dataset.
Part A. SPSS Assignment
The “Activity 6.sav” file contains a datasetof a high school teacher interested in determining whether his students’
test scores increase over
the course of a 12 week period.In the dataset,you will find the following variables:
Participant:unique identifier
Gender: Male (M) or Female (F)
Score_0 – score on the initial course pre-test(firstday of class)
Score_2 – score at the end of week 2
Score_4 – score at the end of week 4
Score_6 – score at the end of week 6
Score_8 – score at the end of week 8
Score_10 – score at the end of week 10
Score_12 – score at the end of the course (week 12)
To complete this Activity
1. Exploratory Data Analysis.
a. Perform exploratory data analysis on the relevant variables in the dataset.When possible,include appropriate
graphs to help illustrate the dataset.
b. Compose a one to two paragraph write up of the data.
c. Create an APA style table that presents descriptive statistics for the sample.
2. Repeated-Measures ANOVA. Perform a repeated-measures ANOVA using the “Activity 6.sav” data set. You will
use Score_0 through
Score_12 as your repeated measure (7 levels),and gender as a fixed factor.
a. Is the assumption ofsphericityviolated? How can you tell? What does this mean in the context of interpreting the
results?
b. Is there a main effect of gender? If so,explain the effect. Use posthoc tests when necessaryor explain why they
are not required in this specific case.
c. Is there a main effect time (i.e., an increase in scores from Week 0 to Week 12)? If so,explain the effect. Use post
hoc tests when necessaryor explain why they are not required in this specific case.Examine the output carefully and
give as much detail as possible in your findings.
d. Write up the results in APA style and interpretthem.Be sure that you discuss both main effects and the
presence/absence ofan interaction between the two.
Part B. Applying Analytical Strategies to an Area of Research Interest
3. Briefly restate your research area of interest.
a. Identify at least2 variables for which you would utilize a repeated-measures ANOVA in your analysis.Describe the

2. variables and their scale of measurement.Identify whether each factor is fixed or repeating.Where on the SPSS
output would you look to find out if you violated the assumption ofsphericity? If the data did violate this assumption,
what would the impactbe on your analysis?
Your submittal should demonstrate thoughtful consideration ofthe ideas and concepts thatare presented in the
course and provide new thoughts and insights relating directlyto this topic. Where applicable your submittal should
reflect scholarlywriting and current APA standards.
Review APA Form and Style.
