When in doubt about anything at all, ask questions!!!
ALL students are expected to be familiar with all the topics covered within the required prerequisites to be in this course. That is, courses covering linear and matrix algebra and STA 360 or 601 or 602L. Students are also expected to be very familiar with R and are encouraged to have learned LaTeX or a Markdown language by the end of the course.
Work hours will include time spent going through the preassigned readings, watching the lecture videos, watching or attending the lab sessions, and doing all graded work. Please note that the more focused and engaged you are, the quicker you will be able to get through all the materials.
Graded work for the course will consist of problem sets, lab exercises, two case studies and two exams. Regrade requests for problem sets, lab exercises and case studies must be done via Gradescope AT MOST 24 hours after grades are released! Regrade requests for the exams must be done via Gradescope AT MOST 12 hours after grades are released! Always write in complete sentences and show all of your steps.
Students' final grades will be determined as shown below:
|Lab Exercises & Overall Participation||10%|
|Group Case Study I||10%|
|Group Case Study II||15%|
There are no make-ups for any of the graded work except for medical or familial emergencies or for reasons approved by the instructor BEFORE the due date. See the instructor in advance of relevant due dates to discuss possible alternatives.
Grades may be curved at the end of the semester. Cumulative averages of 90% -- 100% are guaranteed at least an A-, 80% -- 89% at least a B-, and 70% -- 79% at least a C-, however the exact ranges for letter grades will be determined at the end of the course.
Descriptions of graded work
Four problem sets will be handed out over the course of the semester. These problem sets are to be completed independently without collaborating with other students. Be sure to check the website regularly for the dates and deadlines! Please note that any work that is not legible by the instructor or TAs will not be graded (given a score of 0). Every write-up must be clearly written in full sentences and clear English. Any assignment that is completely unclear to the instructors and/or TAs, may result in a grade of a 0. For programming exercises, you are required to use R and you must submit ALL of the code as an appendix.
Each student MUST write up and turn in her or his own answers. You are encouraged to talk to each other regarding homework problems or to the instructor/TA. However, the write-up, solution, and code must be entirely your own work. The assignments must be submitted on Gradescope under ``Assignments''. Note that you will not be able to make online submissions after the due date, so be sure to submit before or by the Gradescope-specified deadline.
Solutions will be curated from student solutions with proper attribution. For each problem set, the TAs will select a representative correct solution for the assigned problems and put them together into one solutions set with each answer being attributed to the student who wrote it. If you would like to OPT OUT of having your solutions used for the class solutions, please let the Instructor and TAs know in advance.
The objective of the lab assignments is to give you more hands-on experience with hierarchical data analysis. Join the live sessions or watch the recorded videos and learn a concept or two and some R from the TAs, and then work on the computational part of the problem sets. Each lab assignment should be submitted in timely fashion. You are REQUIRED to use R Markdown to type up your lab reports.
Group Case Studies
There will be detailed analysis of two case studies using current, relevant data. Each case study will involve a final submission per team. Each team will create/record video presentations of their findings to be viewed by the other teams, and also turn in written reports. You must participate in each video presentation to receive full credit for that group case study. Individual contributions to each submission will also be assessed. Team members must provide these assessments in order to receive credit for an assignment. An individual team member’s grade may be modified if assessments indicate this is appropriate. Additional details on the case studies will be made available later.
There will be two exams as specified on the syllabus and schedule. If you know in advance you must miss an examination, please contact the instructor as soon as possible. Detailed instructions will be made available later.
Late Submission Policy
You will lose
- 40% of the total points on each problem set or case studies if you submit within the first 24 hours after it is due, and
- 100% of the total points if you submit later than that.
In addition, you will lose
- 50% of the total points on each lab exercise if you submit within the first 24 hours after it is due, and
- 100% of the total points if you submit later than that.
You will lose 100% of the total points on exams if you miss the dates/times.
Students who audit this course will be expected to complete most of the graded work with the goal of getting an overall score of at least 70%; you will only need to complete enough graded work to get to 70%. You are also expected to watch the videos, go through the readings, and generally, participate like everyone else. You must contact the instructor in advance if you wish to audit the course.

Try as much as possible to refrain from texting or using your computer for anything other than coursework while watching the lecture videos or during the live sessions. Again, the more engaged you are, the quicker you will be able to get through the materials. You are responsible for everything covered in the lecture videos, lecture notes/slides, and in the assigned readings.
