You are the Director of Institutional Research at a small state university and you have been given

 

the task of gathering information for the Dean of the School of Education regarding the

 

performance of its undergraduate students on the Graduate Record Exam (GRE). Data on six

 

variables were collected: gender, overall grade point average (GPA), major GPA, GRE scores in

 

major area, GRE quantitative, GRE verbal, and type of preparation programs. The university is

 

dedicated to maximizing student success on the GRE. The university has established five

 

different options for students to prepare for the GREs: option 1 = completely online

 

asynchronous prep course, 2 = completely online synchronous prep course, 3 = complete a

 

hybrid prep course with a combination of online and face to face; 4 = complete a traditional

 

instructor led prep course, and 5 = self-paced paper based prep course.

 

The Dean has simply said to you, ?Tell me what works best and for whom?? You decide to

 

establish a pilot study with 50 randomly selected general science education seniors to determine

 

the details of the methodology as well as to provide some initial data and corresponding results

 

to learn if the research plan meets the Dean?s needs. The pilot study needs to contain the

 

following components written in APA format:

 

Part 1:

 

1. Develop a clear purpose statement sentence capturing the essence of the intent of the pilot

 

study.

 

2. Develop a brief introduction including three research questions (with the use of

 

corresponding symbols or Q1., Q2., Q3.) related to the purpose of the pilot study.

 

3. For each of the three research questions, develop a null and alternative hypothesis (with

 

the use of corresponding symbols or Ho1:, Ha1:, Ho2:, Ha2:, Ho3:, Ha3:).

 

4. Using a statistical decision chart similar to Gragetter and Wallnau (2013) Chapter 19,

 

select the appropriate statistical test/analysis for each research question. Briefly explain

 

the choices for each research question.

 

5. Conduct each analysis using SPSS with the SPSS data set below. The output of those

 

tests should be placed in an Appendix for the final report to the Dean.

 

6. Present and discuss the findings (as related to each research question and the fail to reject

 

or rejection of each null hypothesis) in APA format.

 

Part 2:

 

1. Report appropriate descriptive results.

 

2. Present the results in a logical fashion, answering the research questions and testing the

 

hypotheses as stated and in an appropriate manner for the type of data collected.

 


 

3. Identify the assumptions of statistical tests, explain the conducted tests to determine

 

whether those assumptions were met, and discuss any violations of those assumptions.

 

4. Make decisions based on the results of the statistical analysis, such as whether the results

 

were statistically significant, and include relevant test statistics and p values.

 

5. Refer to the APA Manual for guidance on how to present the results in the text, tables,

 

and/or figures.

 

6. Present sufficient information so the Dean can make independent judgments about the

 

findings.

 

Data

 


 

In this mock data file there are 50 participants and 6 variables:

 


 

Variable column 1: Gender 1=male, 2=female

 

Variable column 2: overall grade point average (gpa) based on a 4 point system

 

Variable column 3: major gpa based on a 4 point system

 

Variable column 4; Graduate Record Exam (GRE) in major

 

Variable column 5; GRE quantitative

 

Variable column 6: GRE verbal

 

Variable column 7: Preparation Approach
