**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:**

The purpose of this course is to provide students with the quantitative skills that are necessary for doing apppied work. In order to accomplish that goal, the teacher must facilitate learning and the student must learn the required materials. This requires feedback from the student to the teacher. This feedback occurs in written work and classroom discussion.

The homework is intended to assess what students know and what they are uncertain about. Homework is graded liberally and based on effort while the examinations and papers are graded on achievement.

**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.

**Instructor Learning Outcomes**

- Give an oral report to the class on your research paper

**Core Assessment:**

**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). This proposal should include the following four items.

**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 the primary independent 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). They should be in this order: dependent variable, primary independent variable, and remaining three independent variables.

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

For the primary independent variable, you must also cite two research sources that discuss the variable. The sources need not be technical documents. List these sources on the Works Cited Page.

**3) Data Description**

You must have at least 30 observations of cross-sectional data for each of the five variables. Thus for the final paper, you will have a data matrix that is at least 30 rows by 5 columns.

In one paragraph, describe the data (i.e., which government agency supplies the data, what methods are used to compile them, when they were collected, etc.) and identify the specific data sources, including table numbers. Include the data sources on your Works Cited page. Attach a Xerox copy of the data set to the end of the proposal.

**4) Works Cited Page**

The final page of your proposal should be a Works Cited page on which you list the two research sources for the primary independent variable in the appropriate format. You should also list the data sources, with a separate citation for each table of data.

### Final Research Paper

__Purpose Statement and Model__

1) In the introductory paragraph, state why you have chosen to analyze the dependent variable. 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 you've found that support your thesis, i.e., your model. (Definitions or citations from encyclopedias are not acceptable.)

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. State your expectations for each independent variable. (one paragraph for each variable, in numerical order, i.e., X_{1} first, then X_{2}, etc.)You should address the following:

< How is the variable defined in the data source?

< What unit of measurement is used?

< For the independent variables: WHY does the variable determine Y?

< What sign do you expect 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 did you take the data? (Citing a website is not acceptable.)

< What 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 you have a low adjusted R^{2}, how has your 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 your 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 you 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 your 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 your model.

11) Other (not required):

< If you use any of the techniques for improving results discussed in class, discuss these at the end of the paper.

**Works Cited Page**

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

__12) Research: two sources____ __

13) __Data__: a separate citation for each variable

Link to Class Rubric**Class Assessment:**

**Problem Sets: **Problem sets are graded liberally and a solution set will be provided to the students. The purpose of the problem sets is to assess your learning of the material. The completion of the problems sets will facilitate your success on the examinations. Should you have any questions about the problem sets, you will need to get it resolved before the examinations.

**Examinations: **The examinations will be primarily composed of applications and interpretations, in addition to a small set of multiple choice and/or true false questions. The only refererence allowed during the examinations will be the **GUIDE.**

**Term Project: **The term project involves proposing a model and then writing a formal proposal for the research it involves. The student will use Excel to regress data for their model. The student will analyze the computer output and write and submit a written report. See **Guide** for details on the various requirements for the written paper. Each item turned in will have a cover paper with the student's name.

**Oral Report: ** See additional Oral Report requirements and suggestions in Chapter 14 of the **Guide, **along with an Oral Report Checklist

**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.
