Zero points are given for unacceptable or assignments not turned in. A score of 1 is given for an acceptable assignment. Assignments are due at the end of the class period. Late assignments are not accepted. Twenty-five of the 26 available assignments count toward the grade.

Five quizzes will be given, each worth 10 points. Four of the five quizzes count toward the grade. No make-up quizzes are given. Quizzes count toward 40 points of the overall grade.

The research report is worth 35 points. It is composed of several open-ended questions similar to the assignments. The reports involve analyzing data and students are given the choice of what research question to investigate. Reports are due at the regularly scheduled final exam date during finals weeks.
