Exam Logistics and Policies
1. What is the official date and time range for Midterm 1?
Answer: The exam window opens on Thursday, February 19th, 2026, at 8:00 PM
(CT) and closes on Sunday, February 22nd, 2026, at 11:45 PM (CT) .
Explanation: Students may begin the exam at any point during this window. Once
started, the exam will be automatically submitted when the window closes, regardless
of the remaining time.
2. How much time is allocated to complete the exam, and what is the penalty for late
submission?
Answer: Students have 2 hours to complete the exam once they begin. The penalty
for late submission is -10 points per minute after the 2-hour time limit.
Explanation: It is crucial to manage your time effectively. The late penalty is strictly
enforced to ensure fairness for all students. Submitting a few minutes late can
significantly impact your final score.
3. What materials are permitted during the exam, and what must be submitted
afterward?
Answer: Permitted materials include:
o One double-sided or two single-sided sheets of reference notes on Letter size
(8.5" x 11") paper.
o A physical calculator (non-communicating).
o Blank scratch paper.
o Submission: Both your reference notes and scratch work must be submitted
within 30 minutes after submitting the exam.
, Explanation: The reference notes and scratch work are graded alongside the exam.
To ensure your scratch work is reviewed, clearly label your answers and, if applicable,
type “see notes” in the answer box.
4. What is the official proctoring platform, and what are the key technical protocols?
Answer: The exam is proctored through ProctorU using the Guardian Browser. In
case of technical issues, students must contact ProctorU or the Teaching Support
Team directly, as the instructor does not have the authority to resolve these issues.
Explanation: To avoid red-flagged reports, ensure you complete the mandatory 'End
Survey' after your session. If you exit without completing it, contact ProctorU
immediately. Have a verifiable ID ready for identity verification and avoid talking,
using earbuds, or having pets present during the session.
5. What is the recommended strategy for choosing an exam start time?
Answer: It is recommended to take the exam early during typical working hours
(9:00 AM – 5:00 PM).
Explanation: Choosing a start time within these hours ensures that technical support
staff are readily available should any issues arise.

6. What are the two primary types of observations, and what are their subtypes?
Answer: The two primary types are categorical (qualitative) and numerical
(quantitative) . Numerical data is further classified as discrete (countable) or
continuous (measurable).
Explanation: Correctly identifying variable types is the first step in selecting
appropriate statistical methods. Categorical data represents groups or categories,
while numerical data represents measurable quantities.
7. What is the difference between frequency and relative frequency?
Answer: Frequency is the count of occurrences for a specific value or
category. Relative frequency is that count divided by the total number of
observations, representing the proportion or percentage.
