CBTF Policies

Please be aware of the CBTF policies:

Academic Integrity

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:

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.


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


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.
