Note Two sections of introductory statistics were taught by the same
instructor. Grading is on a scale from 0.0 to 4.0 in increments of 0.1. A
project is a written report and oral presentation involving data analysis by
teams of 3-4 students. Each team member of the team gets the same grade
except for unusual slackness or leadership (team members rate one
anothers' contributions). A homework is an individual set of independent
learning exercises. A popquiz is an unannounced closed-book 20-minute
problem/essay test over topics covered in the last 1-2 weeks. A quiz is an
announced 30-minute multiple-choice/problem/essay test that covers 4-5
weeks' material. An exam is an announced multiple-choice/problem/essay
test covering everything in the previous 6 weeks. SemAverage is the
percent grade received in the class, which may include adjustments by the
insructor for trend, outliers, or effort.
