# CBTF Policies

Please be aware of the CBTF policies:

In short, do not cheat. In addition to the Academic Integrity policies outlined by the CBTF, STAT 432 will hold itself to a higher standard. Any violation will be punished as harshly as possible, which at minimum is a failing grade on the exam.

A non-exhaustive list of academic integrity violations:

• Informing another student of your exam date and time.
• Informing another student about exam material, generally or specifically.

You are correct that some of these things may be hard to detect, but in addition to writing the exam in a manner that makes transferring this type of information less useful, we have other methods that you are likely unaware of to detect the above violations.

Be aware that the exam window goes until Friday. However, this does not mean that you may discuss the exam at that time as there may be makeup exams in rare circumstances. Do not discuss any part of the exam until I announce that it is OK to do so.

# Content

All course content through Friday, September 27, with emphasis on the material that has been assessed in the quizzes. (Quiz 01 - Quiz 06.)

# Format

You will be given 50 minutes to complete the exam which will be administered through PrairieLearn. You will have access to RStudio with a large set of packages installed. (Those seen in the quizzes.)

# Provided Notes

$\text{Sensitivity} = \frac{\text{TP}}{\text{P}} = \frac{\text{TP}}{\text{TP + FN}}$ $\text{Specificity} = \frac{\text{TN}}{\text{N}} = \frac{\text{TN}}{\text{TN + FP}}$

These, and perhaps other similar definitions (related to binary classification) will be provided with any relevant problems. No additional materials will be provided.

# FAQ

How many problems are on the exam?

• This question is irrelevant since each problem could have an arbitrary number of parts. A one problem exam could easily be written to be longer than a ten problem exam.

How long will it take to do the exam?

• If you are well prepared and manage your time efficiently: Under 50 minutes.
• If you are ill prepared or manage your time poorly: Over 50 minutes.
• You should not focus on this. Focus on practicing and being able to do questions of the types you’ve seen on quizzes. Let me worry about this. And believe me, I worry about this a lot.

Will the exam be curved?
