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
DESCRIPTION OF CORE ASSESSMENT FOR EC 315:
All Park University courses must include a core assessment that measures the course Learning Outcomes. The purpose of this assessment is to determine if expectations have been met concerning mastery of learning outcomes across all instructional modalities. For this course, the core assessment is a research project that includes a written proposal and final research paper. This project is worth 20 percent of the student's final grade and will assess students' mastery of four core learning outcomes (Learning Outcomes 1, 2, 3, and 4 listed on this syllabus).
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.
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 X1:
The model is:
Y: brief definition of Y
X1: brief definition of X1 [etc. for each variable]
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., X1 first, then X2, 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?
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?
6) Write the estimated (prediction) equation:
The results are:
7) Identify and interpret the adjusted R2 (one paragraph):
< Define “adjusted R2.”
< What does the value of the adjusted R2 reveal about the model?
< If you have a low adjusted R2, 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 RubricClass 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
PowerPoint presentations should follow the 3-5-7 rule. No more than 3 main points per slide, no more than 5 lines of dense text, and no more than seven words per line.

Late Submission of Course Materials:
Problem sets are due at the start of class one week after it is assigned. Place the problem sets on the instructor's desk as you enter the classroom. The solutions will be passed out at the beginning of class and discussed. Homework turned in late will be grade for completeness and will be given a maximum grade of 50%.
