Contact Information

Dr. Trung Ly

In addition to class meetings and office hours, email is the primary mode of communication between you and me throughout this course. You are required to check your university-assigned email account for all class instructions and updates. You are encouraged to ask questions via email but should expect that it may take up to 24 hours to receive a response. If you do not receive a response after 24 hours, please follow up with another email. Due to the large number of emails I get on a daily basis, please start the subject line with "ECON 3402-XX", where XX is the section number.

All email correspondence should be professional, and should make use of a salutation, a sign-off, proper grammar, and as little slang as possible. This policy is not to encourage formality for its own sake, but rather to build habits to prepare you for your professional life after graduation.

Note: the only email I check is the one listed above. I NEVER check the mailbox that is provided within CourseDen.

Office Hours

  • Mondays, Wednesdays, 3:30 PM to 5:00 PM
  • Tuesdays, Thursdays, 2:00 PM to 4:00 PM
  • By appointment (please send me an email to make an appointment)

All office hours are held virtually (online). In order to attend office hours, I ask that you sign up at this link ( Once you make an appointment, you will receive a confirmation email with the date and time and a link to join the online meeting with me via Google Meet. If you use a computer, you just have to click on the link in the email. If you use a mobile device (phone or tablet), you may have to install Google Meet, which is a free app.

Meeting Times

To ensure social distancing guidelines are followed, UWG will employ dual modality delivery for the Fall 2020 semester. This has the following implications:

1. Instructional materials will be provided online through YouTube videos in which I walk you through the material as if you attend lectures in person. The videos are uploaded to my YouTube channel (Link:; this link is also posted in an announcement on CourseDen).

Videos are organized into different playlists. The videos in each playlist are arranged in the order that you should watch them, so just watch the playlists in the preset order, i.e. do not shuffle. The playlists are numbered, and you should watch them in the order from the smallest-numbered playlist to the largest-numbered one.

2. Only about 50% of the roster should be in a room at one time. Please following the following assignment to attend in-person lectures:

Section 02: (room Miller Hall 2201)

  • Mondays 09:30 am - 10:45 am (last names A-K)
  • Wednesdays 09:30 am - 10:45 am (last names L-W)

Section 03: (room Miller Hall 2201 1309)

  • Mondays 11:00 am - 12:15 pm (last names A-J)
  • Wednesdays 11:00 am - 12:15 pm (last names M-W)

Section 04: (room Miller Hall 2214)

  • Mondays 02:00 pm - 03:15 pm (last names A-L)
  • Wednesdays 02:00 pm - 03:15 pm (last names M-Z)

During face-to-face class meetings, we will go over any questions about the online content and do practice problems.


Statistical Techniques in Business and Economics

  • Author: Douglas Lind and William Marchal and Samuel Wathen
  • Publisher: McGraw-Hill
  • Edition: 18

The textbook used in this course is Statistical Techniques in Business and Economics by Wathen, Lind, and Marchal, 18th Edition. We use the Connect software that accompanies the textbook for problem sets and exams (more on Connect assignments below). You can purchase an access code through McGraw-Hill or from the bookstore, though purchasing it from the bookstore is more expensive. The access code gives you access to Connect as well as an eBook within the software.


LO1-Construct and interpret tabular and graphical methods of presenting qualitative and quantitative data (LG2, LG3, LG10)

LO2-Construct and interpret summary and numerical measures of location, variability, and association for the sample and the population (LG2, LG3, LG10)

LO3-Apply basic probability concepts, expected value and variance to a variety of different business applications (LG2, LG6, LG10)

LO4-Use discrete and continuous probability distributions and sampling distributions in a variety of business applications (LG2, LG3, LG6, LG10)

LO5-Construct and interpret interval estimates and hypothesis tests (LG2)



Final grades for the course are based on the following:

Types of evaluations and related weights

Grade Range Notes
A 90%+
B 80%-89.99%
C 70%-79.99%
D 60%-69.99%
F Below 60%


Problem sets

There is generally a problem set for each main topic (each YouTube playlist) covered in class. These problem sets are administered on Connect. You can do these problem sets as many times as you want. Only the scores from your best attempts are used to calculate your grade. Doing it this way allows me to set the due dates for the problem sets to be the day Fall classes end (November 25, 2020) while at the same time making it possible for you to practice as much as possible to prepare for the exams. The purpose of these problem sets is twofold: first, they allow you to apply what you learn in lectures to specific problems; and second, they help you become familiar with Connect.


Several quizzes are be given throughout the semester. These quizzes are available under the Assessments drop-down menu on CourseDen. Questions on these quizzes are directly related to the content of the videos I post on YouTube. If you watch the videos and take notes, you should ace all these quizzes. The content of each quiz is obvious from the title of the quiz. 

All quizzes will be due at 11:58 pm on the day Fall classes end (November 25, 2020).


There are two midterm exams and one final exam, both of which are administered on Connect. There are two things you have to do for each exam:

  1. Answer the questions and submit your exam on Connect.
  2. As you work on the exam questions, you should be writing down how you arrive at the answers on separate sheets of paper. Within five (05) minutes of when you submit your exam on Connect, you have to take pictures of your written work and submit them on CourseDen by going to the Assignment section under the Assessments drop-down menu. If possible, please submit them as one Word of PDF file, but this is not necessary.

Your written solutions should show all your work. If you don't show all the work leading up to the final answers you submit on Connect, you will not get full credits even if your final answers (on Connect) are correct. It is your responsibility to ensure that your written solutions are legible and that the quality of the photos is acceptable. What you submit to me should be something you feel comfortable submitting if this were a traditional face-to-face course. In other words, think of this as submitting an exam in a traditional face-to-face course. 

Five points will be deducted for every minute your written solutions are submitted late. If you do not submit your written solutions at all, I will still grade your work on Connect, but the official numerical score you will get (the score that will be used to compute your letter grade) will be half of what you get on Connect.

If there is anything that you feel prevents you from fulfilling this portion of exams, please let me know within the first week of the course.


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.

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!

Institutional Policies

Academic Support

Accessibility Services: Students with a documented disability may work with UWG Accessibility Services to receive essential services specific to their disability. All entitlements to accommodations are based on documentation and USG Board of Regents standards. If a student needs course adaptations or accommodations because of a disability or chronic illness, or if he/she needs to make special arrangements in case the building must be evacuated, the student should notify his/her instructor in writing and provide a copy of his/her Student Accommodations Report (SAR), which is available only from Accessibility Services. Faculty cannot offer accommodations without timely receipt of the SAR; further, no retroactive accommodations will be given. For more information, please contact Accessibility Services.

Center for Academic Success: The Center for Academic Success provides services, programs, and opportunities to help all undergraduate students succeed academically. For more information, contact them: 678-839-6280 or [email protected]

University Writing Center: The University Writing Center assists students with all areas of the writing process. For more information, contact them: 678-839-6513 or [email protected]

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:

You may also visit our website for help with USG Guidance:

Mental Health Support

If you or another student find that you are experiencing a mental health issue, free confidential services are available on campus in the Counseling Center. Students who have experienced sexual or domestic violence may receive confidential medical and advocacy services with the Patient Advocates in Health Services. To report a concern anonymously, please go to UWGcares.

ELL Resources

If you are a student having difficulty with English language skills, and / or U.S. culture is not your home culture, specialized resources are available to help you succeed. Please visit the E.L.L. resource page for more information.


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.

Student FAQs: For more information about UWG COVID-19 guidance for students visit the Student FAQ webpage


Additional Items


My goal is to use in-class meetings to (i) go over important points that you should know and retain from watching the online videos, (ii) answer any questions you may have about the online content, and (iii) solve practice problems (e.g. homework problems on Connect). There is no penalty for not attending. If you decide to come to class, I expect you to behave in a professional manner. Therefore, please do not insult, belittle, or make fun of other students in class. Do not misbehave in class (think excessive talking and disrespect). If an incident occurs, you will be dismissed from my class for the rest of the class. In addition, to ensure everyone's health and safety, please wear your face covering (mask) appropriately (see the section on masks below).

Face coverings (Masks)

Please wear your mask properly. A mask should cover BOTH your nose AND mouth. Here is one of many good resources out there that show you how to wear your mask the right way ( 

You will be asked to leave the classroom if you do not wear a mask or if you wear one but your mask does not cover both your nose and mouth.

Electronic devices

Unless otherwise announced, please do not use electronic devices in class. The use of a laptop is allowed for note-taking only. Personally, I advise against using electronic devices for this purpose, and here is a link to an article explaining why ( Do not text, listen to music, or surf the internet.
