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 quizzes, problem sets, and exams. I will give 14 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 four scores are dropped automatically. Each quiz is timed. Quizzes are worth a total of 120 points.

There are two Excel problem sets and two non-Excel problem sets. The non-Excel problem sets are worth five points each and are graded based on completion only. The Excel problem sets are worth fifteen points each and are graded for accuracy. In addition, there is a take-home, online Excel regression project worth twenty points.

There are three exams. Each exam is worth 40 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:

40% Quizzes (top 10 scores out of 14 quizzes), 120 total points.
20% Problem Sets and Regression Project, 60 total points.
40% Exams (three exams, they all count for 13.33% each, none of them are dropped). 120 total points.

The class is worth 300 points.

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).
