Course description: ECON 4630 is a course intended to prepare students for more

advanced economics courses, especially ECON 4870. Students will master basic

probability and statistics, estimation and hypothesis testing, as well as other probabilityand statistics topics. Emphasis will be placed on applications from economics. Students

in this class are required to register for and attend one of the 1-hour lab sessions taught inGateway 141. In this lab session students will learn how to use software packages such as

MS-Excel to research statistical questions.

This course is NOT for students who have completed or plan to take DSCI3710,MATH3680, or MATH4650. If you have taken one of those courses, you may not get

credit for taking this course. Please, consult with your academic advisor. If you havecompleted one of the courses equivalent to ECON4630, you should consider ECON 4870

(Introduction to Econometrics) or other courses of your interest.

2. Problem sets:a. There will be 8 problem sets. The best 7 problem sets will count towards

your final grade.

b. Problem sets are due at or before the beginning of class. Late problemsets will NOTbe accepted (you may turn in early). Due dates will be

clearly marked on each problem set. While general consulting with fellowstudents on the assignments is acceptable, each student must do the

assignments by themselves. Failure to do so will be considered cheating

(see policy below).

3. The Research Project: multiple regression analysis of your data on the topic youhave selected. Please refer to the instruction on page 5 of this syllabus.

a. The research project is due by 11:59 p.m. on Wednesday, December 4th.Both the paper (Microsoft Word or PDF format) and the excel data file

must be emailed to kwon@unt.eduby the due date.b. Your paper will be checked for plagiarism at turnitin.com or elsewhere.c.

The penalty will be assessed for late submission. The full percentagepoints for the paper (100 points) will be reduced by 20 points for each

additional day after the due date. NO EXCEPTIONS.

4. Exams:a. All the exams will be held at the classroom unless announced otherwise.b. All the exams will be comprehensive. However, the materials discussed

after the previous exam will be heavily emphasized.

c. There will be no makeup exam. If a student misses a midterm exam with avalid, documented University-approved excuse, the student will be

allowed to count his or her final exam more heavily.

d.

The final exam is scheduled on Tuesday, December 10

th

from 10:30amto 12:30pm. Except for those with a valid University-approved excuse,

everyone is required to take the final exam at the scheduled time.e. If a student misses an exam without a valid University-approved excuse,

he or she will be given a score of zero.

5. Lab grade will be assigned by the lab instructor.6. Attendance:

a. In addition to reading the textbook and completing the course assignments,students will find regular attendance in class necessary in order to fully

grasp the topics covered in ECON 4630. Students are urged in thestrongest possible terms to be present at each and every class meeting.b. If a student misses a class, he or she is responsible for class materials or

any class announcement, and should check with classmates regarding what

has been covered or announced.c. To help encourage attendance, unannounced in-class exercises will be

given for extra credit. Students missing a class for any reason will not

receive any extra points if an exercise is given that day.

4630 Research Project

Due Date: Wednesday, December 4th

, 2013

For our final project, we will be putting all that weve learned together. Gather data on a

subject of interest to you. You should collect data on a dependent variableand at least

two explanatory variables. At least one of your explanatory variables must becontinuous; the other can be a dummy variable if you wish. You may gather secondary

data (that is, from books, statistical sources, etc.) or you can collect your own. Here aresome examples from the past (also, some suggestions are attached to this document):

Daily sales at a car dealership as a function of day of the week and years ofexperience of salesperson

Tip percentage at a restaurant as a function of total bill and whether or notcustomer charged the bill.

U.S. imports as a function of the exchange rate and U.S. GDP.You are advised to select a problem that is interesting to you and to discuss your topic

with your instructor if you have concerns.

Your job is to use multiple regression to analyze your data. Specifically, Im looking for

the following:

a. A description of your variables and their source. Make sure to specify which isthe dependent variable and which are the explanatory variables. Include a table of

summary statistics and discuss the statistics in the table.

b. A set of hypotheses for each explanatory variable that reflects how you think eachis related to the dependent variable.

c. Regression output from Excel.d. A careful interpretation of the estimated coefficients on your explanatory

variables.

e. A careful explanation (by referring to hypothesis tests) of whether or not theestimated coefficients are statistically significant.

f. A brief discussion of your R2and its meaning.g. A paragraph summarizing your findings.

NOTE 1: You will need to turn in this paper in electronic form. In addition, you

must turn in your data in electronic form. Your paper will not have been turned in

until these stipulations are met.

NOTE 2: The 10 points per day penalty applies to late papers.
