Mini-Exam 4 Retake Logistics

• Timeframe: It will open Monday 4/25, 12:01 AM, and close Wednesday 4/27, 11:59 PM.
  • The exam will close at 11:59 pm regardless of when you started.
  • This is so it is during the class’s final exam period.
• It assesses the same thing as Mini-exam 4.
  • You may use things that you have learned that were not in the modules that this exam is testing but you can answer it without knowing any modules beyond what this exam is testing.
• The data sets and events will be different.
• You do not need to do both parts. You can only do one part if you wish. You must do ALL of the questions in that part though. We will take the max score per part.
• All other information is similar to Mini-Exam 1’s. Such as getting the files, Gradescope, Sakai, asking for help, grading policy, etc.

Mini-Exam 4 Logistics

• Module covered: 9
  • Module 10 is not tested in the mini-exams
• Timeframe: It will open Thursday 4/14, 12:01 AM, and close Saturday 4/16, 11:59 PM.
  • The exam will close at 11:59 pm regardless of when you started.
• The exam will be take-home. It is open book, open note, open internet, but closed to people.
  • This means you cannot communicate with anyone about the exam, including asking someone through the Internet (like stackoverflow) for help and receiving help.
• Like prior mini-exams, it consists of 2 parts that each have a time limit of 2 hours. Both parts will have data sets and they will be different.
• Grading policy specifics
  • Your answer will not be judged on the accuracy of the model, only on how you contextualize it to a simple probabilistic baseline (e.g. if there are 4 categories and they are all equally likely, you compare it to an accuracy baseline of 25%. However, if one category is present 50% of the time, your baseline accuracy would be 50% because the baseline model could just always guess the most popular category).
  • Warning: To provide more fine-grained granularity of measuring mastery, questions are split into smaller parts. This means the number of points per question part is not uniform.
• All other information is similar to Mini-Exam 1’s. Such as getting the files, Gradescope, Sakai, asking for help, grading policy, etc.

Mini-Exam 3 Retake Logistics

• Timeframe: It will open Thursday 4/14, 12:01 AM, and close Saturday 4/16, 11:59 PM.

• It assesses the same thing as Mini-exam 3.
  • You may use things that you have learned that were not in the modules that this exam is testing but you can answer it without knowing any modules beyond what this exam is testing.
• The data sets and events will be different.
• You do not need to do both parts. You can only do one part if you wish. You must do ALL of the questions in that part though. We will take the max score per part.

Mini-Exam 3 Logistics

• Modules covered: 7 and 8
  • Part 1 covers Module 7: Databases & SQL
  • Part 2 covers Module 8: Visualization
• Timeframe: It will open Thursday 3/31, 12:01 AM, and close Saturday 4/2, 11:59 PM.
  • The exam will close at 11:59 pm regardless of when you started.

• Like Mini-Exam 2, it consists of 2 parts that each have a time limit of 2 hours. Both parts will have data sets and they will be different.
• Grading policy specifics
  • Part 1: SQL
    • To earn an Exemplary (full credit), you must generate/format/retrieve the data entirely using SQL and not manipulate the data after querying it from the database. All questions are designed that they can be done entirely in SQL.
  • Part 2: Visualization
    • The figures you plot are expected to be legible. So we strongly recommend learning how to use the aspect parameter that controls the size of the figure so that things like the x-axis labels do not overlap. A figure that is not legible is not eligible for a grade of Exemplary (full credit).
• All other information is similar to Mini-Exam 1’s. Such as getting the files, Gradescope, Sakai, asking for help, grading policy, etc.

Mini-Exam 2 Logistics

• Modules covered: 4, 5, and 6
  • Note: Even though it’s the same number of modules as Mini-exam 1 that does not mean it is assessing the same amount of knowledge. Module 01 was a pre-amble module to remind you all of Python and as a warm-up for the weekly cadence of the class.
• Timeframe: It will open Thursday 3/3, 12:01 AM, and close Saturday 3/5, 11:59 PM.

This post outlines what Mini-Exam 1 will be like.

Exam Logistics

• Modules covered: 1, 2, and 3
• The exam will be take-home. It is open book, open note, open internet, but closed to people.
  • This means you cannot communicate with a person about the exam, including asking someone through the Internet (like stackoverflow) for help and receiving help.
• Timeframe: It will open Thursday 2/10, 12:01 AM, and close Saturday 2/12, 11:59 PM.
  • The exam will close at 11:59 pm regardless of when you started.
• The exam consists of 2 parts.
  • Part 1 consists of only a Jupyter Notebook.
  • Part 2 consists of a Jupyter Notebook and a data set.
  • You will get the zip files inside a Sakai Quiz.
  • You will submit them on Gradescope.
  • You will have 2 hours for each exam part.
    • We do not expect you to need the entire 2 hours for each part, however, it is not uncommon to get lost in a data set and we wanted to account for that.
  • You can rely on the Sakai Quiz timer to tell you how much time you have left.
  • We will use your logged start time in Sakai to track if you submitted on Gradescope on time.
    • If you submit after your allotted time, we will use the last submission within your allotted time. That includes marking it as zero if you do not submit within your time limit (so you will need to rely on the retake for your exam).
    • We recommend you submit to Gradescope periodically (after each problem) so you are not scrambling at the end trying to open Gradescope.
  • You do not need to do anything with Sakai after you retrieve your zip file from the quiz.
  • During your testing period, you can submit as many times as you want to Gradescope. We will take the submission you mark as active, which is your last submission unless you change it using the history.
• The exam must be done individually. It is a violation of class policy if you collaborate in any way with another person (in or not in the class) on the exam. You can only talk to the teaching staff about the exam.
• Protect the integrity of the exam and your exam submission.
  • Do not talk to anyone about the exam during the exam period.
  • Take your exam in a secure location where no one can bother you.
  • Take your exam in a place where you will not be distracted or tempted to talk to someone.
• If you have a question during the exam, ask it as a private new message on the class forum. Or on Zoom if a teaching staff member is on call at that time.
  • We will do our best to always have someone checking the forum, however, we cannot make promises someone will instantly answer your question.
  • The exam is tested for readability, so the wording should be straightforward.
• The Mini-Exam Retake 1 will be during Mini-Exam 2. Your Mini-Exam 1 score will be the max between this exam and the retake.

Grading Scale and Points Allocation

Each section will be graded on a four-step rubric scale as follows.

• E (Exemplary) – Work that meets all requirements and displays full mastery of all learning goals and material.
• S (Satisfactory) – Work that meets all requirements and displays at least partial mastery of all learning goals as well as full mastery of core learning goals.
• N (Not yet) – Work that does not meet some requirements and/or displays developing or incomplete mastery of at least some learning goals and material.
• U (Unassessable) – Work that is missing, does not demonstrate meaningful effort, or does not provide enough evidence to determine a level of mastery.

There are ~100 points possible and fewer than 10 questions. The number of points earned are evenly distributed across the problems based on the number of concepts they are testing. The rubric will be converted to points as follows:

• E = full credit
• S = E_full_credit – 1
• N = E_full_credit * 0.6
• U = E_full_credit *0.2
• Blank = 0

This scheme ensures that earning an E or S on all problems ensures an A. While a single U means an A is very unlikely, which is reasonable since a U on a problem clearly shows a lack of mastery on all the content for this exam.
