Exams

General information

The exams use the BeachBoard quiz system (the same system you will use for submitting the assignments).

Each exam consists of 25 multiple choice questions followed by 5 sets of free response or calculation questions (i.e., calculations all using a common data set or scenario).

You will have 120 minutes to complete each exam once you begin and the exam must be submitted during the time range specified.

Lecture will not meet on the Thursday associated with each exam.

A set of exams from previous semesters below give you a sense of the type of questions likely to be asked. Although these are from the previous fully in-person spring and summer semesters, the questions in the online exams are very similar. You should have the tables of critical values from the website available for reference.

Additional items for the exams this semester

In addition to the lecture videos material, each exam has an additional document or website that must be studied. These are:

Exam #1 will include questions based on the list of cognitive biases at:

Exams from previous semesters

Because semesters vary in the number of class meetings and placement (or absence) of spring break, some topics may move between exams. If an old exam has questions on material that hasn't been covered or is missing a major topic that was covered, you may find it useful to check the other exams for that semester. In particular, these topics move around the most from semester to semester:

The chi-squared (X²) technique
Experimental design
Ethical considerations
Power analysiss
False positives/negatives
Visual display of information
