In order to master a subject like statistics, regular attendance is crucial. However, if you have a fever or are not feeling well, then please do not come to class that day. As long as you let me know the reason for your absence, I will do my best to help you stay caught up and make up any material that you missed. The key is to communicate with me when you aren’t able to attend class.
Tobacco products (including chewing tobacco and e-cigarettes) are not allowed in class.
My office hours are shown on my weekly schedule. I am also available by appointment. If you can’t stop by during my regular office hours, just ask me after class or by e-mail, and I’ll be happy to make an appointment that works for both of us.
The term grade will be based on the results of the examinations and homework.
| Component | Proportion |
|---|---|
| Quizzes | 30% |
| Projects | 20% |
| Midterm 1 | 10% |
| Midterm 2 | 10% |
| Midterm 3 | 10% |
| Final Exam | 20% |
There is a saying that, “you learn math by doing math.” This is very true! During most class periods you will be asked to solve problems in-class. Any problems you do not complete during class become homework problems. I do not collect these problems however. Instead, you may consult your notes & completed classwork during the weekly quizzes.
Every Thursday (except when midterm exams are scheduled) there will be a 10-15 minute quiz on material covered that week. Each quiz will have 3 or 4 problems and will cover material similar to the in-class and take-home problems. During quizzes you are allowed to use your notes and solutions to old class workshop problems. The lowest quiz grade will be dropped from the final average.
There will be three in-class midterm exams and a cumulative final. Typically these exams will be on the Thursday of the week when they are scheduled. The exams will be closed book. You are allowed to use a scientific or graphing calculator during the exams. You may also use your cellphone as a calculator, but you may not use your phone for any other purpose during exams.
There will be four homework projects at the end of the semester. These projects will require you to analyze real world data, make graphs, carry out relevant statistical tests, and explain your conclusions. The projects must by typed using a computer and you can e-mail them to me when they are due. If you wish, you may work with a partner on the project. If you do work with a partner then you can both submit one file together, just be sure that both of your names are clearly listed on the file that you submit. Aside from work with your partner, all work should be your own. Each project will be graded holistically using the following rubric:
The dates listed for the projects on the schedule above are when the projects will be assigned, not when they are due. You will have at least 3 days from when a project is assigned until it will be due.
Students who think they may need accommodations in this course because of the impact of a disability are encouraged to meet with me privately at the beginning of the semester. Students also should contact Melissa Wood, Title IX/504 Coordinator (mwood@hsc.edu, 434-223-6061) to verify their eligibility for reasonable accommodations. Early contact will help to avoid unnecessary inconvenience and delays.
If we need to switch to an online virtual course at any point during the semester, the basic outline and schedule of topics for the course will remain the same. I will provide asynchronous video guided notes and workshops to help learn the material. I will also divide the class into smaller groups and schedule Zoom meetings during our regular class time where we can go over the material in more detail. I may also incorporate a short oral examination as part of one or more of the midterm or final exams. If you know that you will have trouble with Zoom from home, please let me know.
