**Course Description:**

This intermediate level statistics course covers the fundamentals of conducting quantitative research for the social and administrative sciences. The course is organized around a research project on quantitative analysis of data. PREREQUISITES: MA 120 and CS 140. 3:0:3

**Educational Philosophy:**

Welcome to Quantitative Research Methods. Along with your fellow on-line students, you will learn how to conduct quantitative research using computer statistical analysis. You will be helped along the way by the other members of this on-line class as well as by me. I will provide you with numerous tutiorals and various handouts. I will answer questions that you post in the Questions and Answers discussion thread and questions sent by e-mail.

The fundamental goal of this course is for you to learn how to conduct quantitative research and how to report the results in an effective manner. Since this is a learning exercise, it is not important how statistically significant your research is. Rather, it is important that you be able to use the computer software to generate printouts that you can correctly interpret.

**Learning Outcomes:**

**Core Learning Outcomes**

- Write a proposal for a research project on an original multiple regression model with four independent variables.
- Gather data and research articles related to the multiple regression model.
- Use a statistical software package to regress the original model.
- Write a formal research report that defines and analyzes the evaluative information provided by a statistical software package, including the adjusted R-square, F statistic, t statistics, and correlation coefficients for multicollinearity.
- Do hypothesis testing and determine confidence intervals using the t statistic. Also, conduct hypothesis testing using the F and Chi-square statistics.

**DESCRIPTION OF CORE ASSESSMENT FOR EC 315:**

All

**Research Topic Proposal**

As preparation for the final research paper, formulate an original theory about the correlation between *four* measurable independent variables (causes) and one measurable dependent variable (the effect). The topic proposal should include the following four items which serve as the foundation for the final research paper after instructor feedback is given.

**1) Purpose Statement **

In one paragraph, state the correlation and identify the primary independent variable.

State the correlation:

*“The dependent variable _______ is determined by independent variables ________, _________, ________, and ________.”*

Identify and defend the “primary” independent variable, or the variable believed to have the strongest impact on the dependent variable:

*“The most important independent variable in this relationship is ________ because _________.”*

**2) Definition of Variables **

For each variable, write a single definition paragraph (five paragraphs total). Paragraphs should be in this order: dependent variable, primary independent variable, and remaining three independent variables.

In addition to defining the independent variables, defend *why* each determines the dependent variable.

For the primary independent variable, at least *two research sources* that discuss the variable also must be cited. These sources need not be technical documents but should contain evidence to justify the relationship between the primary independent variable and the dependent variable. List these sources on the Works Cited (reference) page. Citations from encyclopedias, abstracts, or non-governmental websites are not acceptable research sources.

**3) Data Description**

For each of the five variables, at least 30 observations of cross-sectional data must be obtained. Thus for the final research paper, a data matrix that is at least 30 rows by five columns must be presented.

In one paragraph, identify the data sources and describe the data (i.e., which government agencies supply the data, which methods are used to compile them, when they were collected, etc.). Attach a Xerox copy of the original data tables from which the data will be compiled after the proposal is reviewed and approved by the instructor.

**4) Works Cited Page**

The final page of the proposal should be a Works Cited page listing the two research sources for the primary independent variable and the data sources, with a separate citation for each table of data, including specific table numbers for each of the five sources. The appropriate format should be employed (see below).

### Final Research Paper

__Purpose Statement and Model__

1) In the introductory paragraph, state why the dependent variable has been chosen for analysis. Then make a general statement about the model:

“*The dependent variable _______ is determined by variables ________, ________, ________, and ________.”*

2) In the second paragraph, identify the primary independent variable and defend why it is important.

*“The most important variable in this analysis is ________ because _________.” *In this paragraph, cite and discuss the two research sources that support the thesis, i.e., the model.

3) Write the general form of the model, with the primary independent variable as X_{1}:

*The model is:*

Y =

*Where *

Y: brief definition of Y

X_{1}: brief definition of X_{1 }[etc. for each variable]

__Definition of Variables__

4) Define and defend all variables, including the dependent variable, in a single paragraph for each variable. Also, state the expectations for each independent variable. These paragraphs should be in numerical order, i.e., dependent variable, X_{1}, then X_{2}, etc.

In each paragraph, the following should be addressed:

< How is the variable defined in the data source?

< Which unit of measurement is used?

< For the independent variables: *why* does the variable determine Y?

< What sign is expected for the independent variable's coefficient, positive or negative? Why?

__Data Description__

__Data Description__

5) In one paragraph, describe the data and identify the data sources.

< From which general sources and from which specific tables are the data taken? (Citing a website is not acceptable.)

< Which year or years were the data collected?

< Are there any data limitations?

__Presentation and Interpretation of Results__

__Presentation and Interpretation of Results__

6) Write the estimated (prediction) equation:

*The results are:*

7) Identify and interpret the adjusted R^{2 }(one paragraph):

< Define “adjusted R^{2}.”

< What does the value of the adjusted R^{2} reveal about the model?

< If the adjusted R^{2} is low, how has the choice of independent variables created this result?

8) Identify and interpret the F test (one paragraph):

< Using the p-value approach, is the null hypothesis for the F test rejected or not rejected? Why or why not?

< Interpret the implications of these findings for the model.

9) Identify and interpret the t tests for each of the coefficients (one separate paragraph for each variable, in numerical order):

< Are the signs of the coefficients as expected? If not, why not?

< For each of the coefficients, interpret the numerical value.

< Using the p-value approach, is the null hypothesis for the t test rejected or not rejected for each coefficient? Why or why not?

< Interpret the implications of these findings for the variable.

< Identify the variable with the greatest significance.

10) Analyze multicollinearity of the independent variables (one paragraph):

< Generate the correlation matrix.

< Define multicollinearity.

< Are any of the independent variables highly correlated with each other? If so, identify the variables and explain why they are correlated.

< State the implications of multicollinearity (if found) for the model.

11) Other (not required):

< If any additional techniques for improving results are employed, discuss these at the end of the paper.

**Works Cited Page**

12) Use the proper format to list the works cited under two headings:

__ Research: two sources__

__Data__: a separate citation for each of the five variables

Link to Class Rubric**Class Assessment:**

**Grading:**

All final exams will be comprehensive and will be closed book and closed notes. If calculators are allowed, they will not be multifunctional electronic devices that include features such as: phones, cameras, instant messaging, pagers, and so forth. Electronic Computers will not be allowed on final exams unless an exception is made by the Associate Dean.

The Proctored final exam for online courses must be passed with a grade of 60% or higher in order to pass the course regardless of the overall average. The grade for students who pass the proctored final will be based on the overall average of homework and tests taken during the course. The proctored final exam must address only material which the student has been taught in class.

**Late Submission of Course Materials:**

**Classroom Rules of Conduct:**

**Course Topic/Dates/Assignments:**

**Academic Honesty:**

Academic integrity is the foundation of the academic community. Because each student has the primary responsibility for being academically honest, students are advised to read and understand all sections of this policy relating to standards of conduct and academic life. Park University 2006-2007 Undergraduate Catalog Page 87-89

Be sure to re-read this if you have any question at all regarding how you might consider sharing homework solutions or other assignments in this course. In no case will you share solutions to the mid term exam, as this should be your own work only.

**Plagiarism:**

Plagiarism involves the use of quotations without quotation marks, the use of quotations without indication of the source, the use of another's idea without acknowledging the source, the submission of a paper, laboratory report, project, or class assignment (any portion of such) prepared by another person, or incorrect paraphrasing. Park University 2006-2007 Undergraduate Catalog Page 87

Be particularly careful with the citations you provide for the data that you will be using in your Term Project Report. If you get the data from a website, please include the URL in your bibliography--you can never provide too much information in a bibliography in this class.

**Attendance Policy:**

Instructors are required to maintain attendance records and to report absences via the online attendance reporting system.

- The instructor may excuse absences for valid reasons, but missed work must be made up within the semester/term of enrollment.
- Work missed through unexcused absences must also be made up within the semester/term of enrollment, but unexcused absences may carry further penalties.
- In the event of two consecutive weeks of unexcused absences in a semester/term of enrollment, the student will be administratively withdrawn, resulting in a grade of "W".
- A "Contract for Incomplete" will not be issued to a student who has unexcused or excessive absences recorded for a course.
- Students receiving Military Tuition Assistance or Veterans Administration educational benefits must not exceed three unexcused absences in the semester/term of enrollment. Excessive absences will be reported to the appropriate agency and may result in a monetary penalty to the student.
- Report of a "F" grade (attendance or academic) resulting from excessive absence for those students who are receiving financial assistance from agencies not mentioned in item 5 above will be reported to the appropriate agency.

**ONLINE NOTE:**An attendance report of "P" (present) will be recorded for students who have logged in to the Online classroom at least once during each week of the term. Recording of attendance is not equivalent to participation. Participation grades will be assigned by each instructor according to the criteria in the Grading Policy section of the syllabus.

Park University 2006-2007 Undergraduate Catalog Page 89-90

The above information is the standard attendance policy--because adequate feedback of solutions to the homework, mid term and Whatsit Problems will occur each Monday, there will be no late work.

**Disability Guidelines:**

Park University is committed to meeting the needs of all students that meet the criteria for special assistance. These guidelines are designed to supply directions to students concerning the information necessary to accomplish this goal. It is Park University's policy to comply fully with federal and state law, including Section 504 of the Rehabilitation Act of 1973 and the Americans with Disabilities Act of 1990, regarding students with disabilities. In the case of any inconsistency between these guidelines and federal and/or state law, the provisions of the law will apply.
