Homework
Homeworks
Homework 5 solutions will be optional. You will turn in your own work for question 4.2 (not splitting the problem within the group).
If you do the Homework 5 solutions, I will drop your lowest solution grade.
*Indicates homeworks for which presentations are also due
**Indicates the problem for which the presentations will be on
Please note that you need to download the .html file to see the LaTeX math properly.
File Naming
For HW Assignments, please use the following file naming: “HW01_LastName_FirstInitial”
For homeworks without R, this should be a pdf file
For homeworks with R, this may be a pdf file (with the code in the pdf) or an html file
For HW Solutions, please use the following file naming: “HW01_G03_Q1.32_LastName_FirstInitial”
For this naming, “G##” will represent your group number and “Q#.##” will represent the question that you are submitting
For homeworks without R, this should be a pdf file
For homeworks with R, this may be a pdf file (with the code in the pdf) or an html file
For HW Presentations, please use the following file naming: “HW01_LastName_FirstInitial”
This should be a video! You can send me a link to a Zoom or Webex recording
- You can share a file via OneDrive!
Rubrics
A total of 1 point will be given for a complete homework. The following rubric will be used:
| 1 point | 0 points | |
|---|---|---|
| Completeness | All problems and parts (like a, b, c, etc.) are thoroughly attempted. Answers can be incorrect or correct. For parts with longer processes and calculations, solution set up and calculations are required. | Entire problems or parts are skipped. -OR- The full process of a problem is not completed through the calculation. |
A total of 12 points is given to the whole group, 3 points per question. For each question, the following rubric will be used:
| 1 point | 0.5 points | 0 points | |
|---|---|---|---|
| Accuracy | All calculations and answers are correct, with clear and logical steps | Minor errors in calculations or reasoning, but most concepts are applied correctly | Major mistakes or incorrect application of statistical methods |
| Understanding of concepts | Demonstrates strong understanding of statistical concepts and their application | Some understanding, but with gaps or misconceptions about certain concepts | Little or no understanding of the key statistical ideas |
| Presentation and clarity | Homework is well-organized, legible, and easy to follow, with clear explanations of steps and reasoning | Work is somewhat disorganized or unclear, but the main points can still be understood | Poorly organized or difficult to understand, with little to no explanation of the work |
Imagine that a fellow student is coming to you and does not know how to do a problem. Your presentation should serve as a guide for that student. They should be able to link key phrases or theorems that you mention to class and follow your clear and correct work from beginning to end. Finally, your final answer is contextualized given the original problem.
Presentations will be graded out of 9 points with the following rubric:
| 3 point | 2 points | 1 point | 0 points | |
|---|---|---|---|---|
| Accuracy | All solutions are correct, with accurate calculations and appropriate use of statistical methods | Most solutions are correct, but there are minor errors or slight misapplications of methods | Several solutions are incorrect or contain significant errors in calculations or methodology | Most or all solutions are incorrect or missing, with little to no evidence of correct application of methods |
| Understanding of concepts | Demonstrates a strong understanding of the statistical concepts, applying them accurately and clearly throughout the presentation | Shows good understanding of the concepts, though there may be occasional errors, unclear explanations of key ideas, or exclusion of an important step. | Shows limited understanding, with several misapplications, gaps in conceptual explanations, or exclusion of an important step | Little to no understanding of the statistical concepts is demonstrated; frequent errors or misconceptions are present |
| Organization and formatting | The presentation is well-organized, with a logical flow that is easy to follow. Sections and explanations are clearly structured. Easy to follow thought process and learn. | The presentation is mostly organized, but some sections may lack logical flow. Fairly easy to follow thought process. -OR- Presentation deserves 3 points but it exceeds 10 minutes. |
The presentation is somewhat disorganized, with several sections lacking clear structure or transitions. Hard to follow thought process. -OR- Presentation deserves 2 points but it exceeds 10 minutes. |
The presentation is poorly organized, with no logical structure. Cannot follow thought process. -OR- Presentation deserves 1 points but it exceeds 10 minutes. |
How to create a video
I think the best way to make your video will be to record a meeting in Zoom or Webex. In either app, you can enter your personal room, then share your screen with your work (or an iPad screen).
I highly recommend that you try out your recording process to make sure everything works! You can make a short video to playback.
You can follow Zoom or Webex’s guide for recording:

Structure
There are three distinct parts to our homework:
| Homework part | Due date | What is required? | Grading |
|---|---|---|---|
| Individual assignment | Date specified above | You will complete the homework assignment, and turn in an individual copy of your work. This will be graded for completion. However, it will be very helpful if you work hard on each problem. | For completion |
| Group solutions | ~ 1 week after assignment is due | With groups of 4, you will make a homework key for 4 questions (that Nicky chooses). Each group member will be in charge of turning in one question’s solutions. You can think of solutions as a written explanation of your thought process or a written teaching of the work to someone new to the problem. This will be graded for correctness. The group will receive the same grade, which is summed across questions. | For correctness |
Individual presentation (May refer to this as videos/meeting) |
HW 3: 11/12 (meetings in week of 11/11) HW 6: 12/8? |
For homeworks 3 and 6, you will need to make a video or meet with me to explain the solutions to one homework problem. Nicky will identify a single problem for the homework (1 of the 4 solutions problems). You can think of presentations as a communication of your thought process or a lesson on the work to someone new to the problem. You will use less than 10 minutes to explain the homework solution. This will be graded for correctness. Example videos will be posted after homework 2. | Graded out of 4 points. 0 indicating no understanding of the solutions. 1 indicating some basic understanding, but missing major steps. 3 indicating that most of the problem is considered, but not necessarily all or all correctly. 4 indicating that all needed parts were considered and correctly solved. |
If you are having any group dynamic issues, please please please come see me earlier rather than later! You do not need to wait for group evals. We will come up with options for moving forward!
