Materials

No materials except access to MS Excel are needed for this class.

Outcomes

After completing this class, students should have a more detailed understanding of how to test a hypothesis, make a forecast, and estimate a regression model, among other things.

Evaluation

Criteria

You will be evaluated solely on your knowledge of the material. There are no grades based on completion and no grades based on participation.

Breakdown

This class consists of problem sets and exams. Unlike the online version of this class, there are no multiple choice quizzes or no multiple choice tests. This is to enhance academic integrity and to allow me the opportunity to see more of the process with which you solve problems.

There are two Excel problem sets and two non-Excel problem sets, worth fifteen points each. In addition, there is a take-home, online Excel regression project, worth thirty points.

There are three exams. Each exam is worth 70 points. You must take the exam on the specified date, no exceptions.

Although normally we have a cumulative, non-optional final for this class, because
of COVID-19, we will just have three tests instead.

To summarize:

10% Regression Assignment, 30 total points.
20% Problem Sets, 60 total points.
70% Exams (three exams, they all count for 23.33% each, none of them are dropped). 210 total points.

The class is worth 300 points. No assignments or exams are dropped.

Assignments

Problem Sets

All Excel Problem Sets need to be submitted in the following format:
lastname_firstname_econ340611am_psxx.xlsx where xx is whatever the specific number/title is.

Please put one problem per worksheet.

All non-Excel Problem Sets need to either be typed up in Word or hand-written on paper, but scanned as a .pdf from your phone. You can download GeniusScan for free from Apple or Google Play to do this. I will not accept any non .docx or .pdf submissions, i.e., no pictures. You are also welcome to just hand it in during class time or to put a physical copy in my mailbox if I'm not there.

Course Policies and Resources

Office Hours:

Tuesday and Thursday morning (in-person), 9:30-10:30 AM and by appointment. My office is through the advising wing on the first floor of Miller Hall, last door on the right.

 

Format

This is a hybrid class, however I will be lecturing 100% of the time. You are only assigned one of two days per week to come to class, either Tuesday or Thursday, because of social distancing. Because of this, you need to watch the video lectures associated with this course for more detailed lectures outside of class that will introduce the material. The videos are designed to be enough for people to learn the material with substantial practice outside of class, however most students find class time to be valuable. If you struggle with math, you need to strongly consider attending class. 

Class time will be dedicated to introducing topics quickly and going over as many problems as possible given time constraints. I will not test anyone on anything that was not talked about in physical class unless I am forced to quarantine because of COVID-19 or we go online.  Based on my experiences in the fall, students who attended class sessions tended to do reasonably well.

Exams are in-person, no exceptions. If you do not believe that it is safe to take a test in a classroom with your peers, I will work to find a private space for you to take the exam.

Academic Misconduct

I take academic misconduct seriously. Cheating includes accessing any external site, such as Chegg, CourseHero, etc., for assistance with this class. If you are struggling, ask me for help.

If I find that you have cheated on an assignment or test, you will receive a zero on that assignment or test. Afterwards, if additional cheating occurs, you will receive an F in the class. No exceptions. In addition, your behavior will be reported to the Office of Community Standards for further sanctions.

College/School Policies

Wolf Pact

Having read the Honor Code for the University of West Georgia, I understand and accept my responsibility to uphold the values described therein and to conduct myself in a manner that will reflect the values of UWG and the Richards College of Business so as to respect the rights of all UWG community members. As a UWG student, I will represent myself truthfully and complete all academic assignments honestly and within the parameters set by my instructor.

I understand and accept that if I am found guilty of violations (through processes due me as a UWG student and outlined in the UWG Student Handbook), penalties will be imposed.

I also recognize that my responsibility includes a willingness to confront members of the UWG community if I feel there has been a violation of the Honor Code.  

Ultimately, I will conduct myself in a manner that promotes UWG as the best place to work, learn, and succeed for my generation, and those to come!

Online Courses

UWG takes students’ privacy concerns seriously: technology-enhanced and partially and fully online courses use sites and entities beyond UWG and students have the right to know the privacy policies of these entities. For more information on privacy and accessibility for the most commonly used sites, as well as technology requirements visit the UWG Online site.

Students enrolled in online courses can find answers to many of their questions in the Online/Off-Campus Student Guide.

If a student is experiencing distress and needs help, please see the resources available at the UWG Cares site. Online counseling is also available for online students.

Honor Code

At the University of West Georgia, we believe that academic and personal integrity are based upon honesty, trust, fairness, respect, and responsibility. Students at West Georgia assume responsibility for upholding the honor code. West Georgia students pledge to refrain from engaging in acts that do not maintain academic and personal integrity. These include, but are not limited to, plagiarism, cheating, fabrication, aid of academic dishonesty, lying, bribery or threats, and stealing. 

The University of West Georgia maintains and monitors a confidential Academic Dishonesty Tracking System. This database collects and reports patterns of repeated student violations across all the Colleges, the Ingram Library, and the School of Nursing. Each incidence of academic dishonesty is subject to review and consideration by the instructor, and is subject to a range of academic penalties including, but not limited to, failing the assignment and/or failing the course. Student conduct sanctions range from verbal warning to suspension or expulsion depending on the magnitude of the offense and/or number of offenses. The incident becomes part of the student’s conduct record at UWG.

Additionally, the student is responsible for safeguarding his/her computer account. The student’s account and network connection are for his/her individual use. A computer account is to be used only by the person to whom it has been issued. The student is responsible for all actions originating through his/her account or network connection. Students must not impersonate others or misrepresent or conceal their identities in electronic messages and actions. For more information on the University of West Georgia Honor Code, please see the Student Handbook.

UWG Email Policy

University of West Georgia students are provided a MyUWG e-mail account. The University considers this account to be an official means of communication between the University and the student. The purpose of the official use of the student e-mail account is to provide an effective means of communicating important university related information to UWG students in a timely manner. It is the student’s responsibility to check his or her email.

Credit Hour Policy

The University of West Georgia grants one semester hour of credit for work equivalent to a minimum of one hour (50 minutes) of in-class or other direct faculty instruction AND two hours of student work outside of class per week for approximately fifteen weeks. For each course, the course syllabus will document the amount of in-class (or other direct faculty instruction) and out-of-class work required to earn the credit hour(s) assigned to the course. Out-of-class work will include all forms of credit-bearing activity, including but not limited to assignments, readings, observations, and musical practice. Where available, the university grants academic credit for students who verify via competency-based testing, that they have accomplished the learning outcomes associated with a course that would normally meet the requirements outlined above (e.g. AP credit, CLEP, and departmental exams).

HB 280 (Campus Carry)

UWG follows University System of Georgia (USG) guidance: http://www.usg.edu/hb280/additional_information#

COVID-19

Proctored Exams/Online Instruction: Students should be aware and plan ahead for the possibility of having to complete all courses and/or exams online or in a proctored environment. This means talking with your instructors about what minimum technical requirements (software and hardware) will be required should your class move online or a student's personal needs dictate. This also includes making plans for internet access at whatever location participation may occur.

Virtual or in-person proctored exams, if your instructor should require them, may result in an additional cost to the student. Please discuss these details with your instructor or see the information provided here.

Face Coverings: Effective July 15, 2020, University System of Georgia institutions, including the University of West Georgia, will require all faculty, staff, students, and visitors to wear an appropriate face covering while inside campus facilities/buildings where six feet social distancing may not always be possible. Face covering use will be in addition to and is not a substitute for social distancing.

Face coverings are not required in campus outdoor settings where social distancing requirements are met. Anyone not using a face covering when required will be asked to wear one or must leave the area.

Reasonable accommodations may be made for those who are unable to wear a face covering for documented health reasons.
