Final Exam
Note: Final exams are not returned! All exam copies will be shredded on the Monday of week #2 of winter
term. If you want to see your final exam you must stop into my office to see the exam. However, you cannot
keep your copy of the exam.
Please print your name clearly on the back of the last page of this exam. Please read the instructions preceding each
section carefully.
You must answer all questions on this exam. Statistics demonstrate that, on average, between 2-5 objective
questions on every exam are ambiguous enough to come out “aberrant” on an item analysis. Therefore, the total
number of points possible on this exam is 106. However, grades will be calculated out of a possible 100 points,
assuming that 2-3 objective questions on this exam are aberrant.
