Contact Information

Dr. Michael Sinkey

I am happy to set up a phone call with anyone who wants, just e-mail me for my cell.

Office Hours

  • Monday, Tuesday, Wednesday, Thursday, Friday, 12:30 PM to 1:00 PM, Virtual

Office Hours are by appointment, contact me for my cell. I am somewhat available almost any day of the week. I put these hours down so as not to conflict with Google Meet times. Will be available many other times.

Meeting Times

Google Meetings

  • Google Hangout Links

This class is online. Lecture will be delivered via YouTube. We will have Google Hangout reviews of the material to coincide with the YouTube lectures that are posted. Reviews are Q & A although I will lecture live if people ask for some additional help in the Google Hangout session.

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

Breakdown

This class consists of quizzes, problem sets, and exams. I will give 15 quizzes during the semester, each of which are worth 12 points. I keep the top 10 scores. If you miss a quiz, it counts as a zero and is not made up. However, your lowest five scores are dropped automatically. Each quiz is timed, 40 minutes. Quizzes are worth a total of 120 points.

I post quizzes for the entire unit at the start of each unit. You may work ahead through each unit at your own pace.

There are four problem sets. I will keep the top three problem sets. Each problem set is worth 15 points. Problem sets are worth a total of 45 points. I highly suggest that students do all four problem sets even though I only keep the top three.

There are three exams. Each exam is worth 45 points. You must take the exam on the specified date, no exceptions. I give a 24 hour window and each exam is timed, 90 total minutes. Although normally we have a cumulative, non-optional final for this class, because of COVID-19, we will just have three tests instead. The third exam will be given on July 23, the final exam date for Session IV. Exams are worth a total of 135 points.

40% Quizzes (top 10 scores out of 15 quizzes), 120 total points.

15% Problem Sets (top 3 scores out of 4 problem sets), 45 total points.

45% Exams (three exams, they all count for 15% each, none of them are dropped). 135 total points.

The class is worth 300 points.

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.

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#
