Grading.

Grades will be determined from percentage of total points earned on a series of quizzes and on programming assignments. A quiz will be given in most classes. The final exam will consist of the equivalent of about three quizzes and is required. The lowest quiz score (not counting the final quizzes) will be dropped. Makeup quizzes will not be given.

The grade breakdown will be as follows:

• Programming Assignments : 20%
• Quizzes : 40%
• Midterm : 15%
• Final : 25%

Cutoffs for grades will be no higher than the following: 90-100, A; 80-89.99, B; 70-79.99, C; 60-69.99, D; 0-59.99, F. Pluses and minuses will be given at the high/low ends of each grade range (no A+'s or D-'s).

• Probability and chance variability:
  Chance. The law of averages. Expected value, standard error, and the normal approximation for probability histograms. Chapters 16-18 FPPA covered briefly in class.

• Sampling:
  Sample surveys. Chance errors in sampling. The accuracy of percentages and averages. A model for measurement error. Chapters 19-24 FPPA.
