Class:San Elijo Campus, Room 501
MTuWTh 4:30 - 6:25 PM
Required Text: Elementary Statistics: A Step by Step Approach, 4th edition

Calculator: A calculator is required for this class. A graphing calculator supporting statistical functions is strongly recommended. Any calculator that supports exponential and logarithmic functions is acceptable. If you are purchasing a graphing calculator for this class, the Math department recommends the TI-83. In addition, there are detailed instructions for using the TI-83 throughout the textbook.
Supplements: The publisher of the textbook makes different companion resources available. None of the supplements are required, but the student solutions manual is recommended. I've provided additional information about the textbook and supplements.
Course Description: An introduction to data analysis. Topics include design of experiments, descriptive statistics, correlation and regression, probability, sampling, estimation, and significance testing. Students will use appropriate technology to analyze real-world data.
Prerequisite: Math 101 with a grade of "C" or better, or qualification through the Math Competency Exam.
Grading: Your grade will be determined by the total number of points that you have accumulated throughout the course. The following scale will be used to determine letter grades A = 90–100%, B = 80–89.99%, C = 70–79.99%, D = 60–69.99%, F = 0–59.99%. Points are awarded as follows:
Activity QuantityPoints Each Total Points% of Grade
Homework 17  75   1275  25
Quizzes 15  68   1020  20
Tests 3  510   1530  30
Final Exam 1  1275   1275  25
Total: 5100  100
Homework: Homework is graded for completeness and correctness. You are expected to do your own work, and you are encouraged to work with others in the class. This is a very important distinction. Here are some guidelines:
• You are encouraged to discuss the homework problems with each other
• You are encouraged to compare ideas about how the problems can be solved.
• You are encouraged to check answers with each other and to compare your completed solutions.
• You must not copy someone else's solution.
• If you find that you've worked very closely with someone to solve a problem, you should do the following:
• Look for another way to solve the problem. Math problems usually have only one answer, but more than one solution.
• Verify that you can solve a similar problem -- perhaps an odd-numbered problem from the text.
• Note on your homework that you solved the problem with someone else, who that was, and what you've done to make sure that you can solve similar problems.

This is a summer session, so the schedule is very short. Homework will be due every day, except the first class, the last class, and test days. The exercises will cover the material from the previous lecture and reading assignments. Homework will be graded promptly. A few exercises from each assignment will be graded for correctness. You will have an opportunity to correct any mistakes and submit your corrections at the next class. So, for example, you will receive a reading assignment on Monday. The lecture on that material will be on Tuesday, and homework from that section will be due on Wednesday. You will normally receive the graded homework back on Thursday, and you can submit corrections on the next Monday.

Late homework is strongly discouraged. You will find that it is almost impossible to catch up. Nonetheless, I realize that many of you will have at least one day when you cannot put in two or three hours between one class and the next. You may submit your homework up to two days late, but you will not have an opportunity to correct mistakes. In addition, for each student, I will accept two assignments one day late, and still give you a chance to correct mistakes—but only twice. Any assignment more than two days late will not be accepted.

There will be one bonus homework assignment due the class before the final exam. If you elect to do this assignment, then you can use this score to replace one homework assignment.

Every student should strive to get every homework point. The grading may be strict, and I may ask you to justify your solution or even do extra work to get full credit. If you rise to the challenge, you will succeed.

Quizzes: There will be a quiz each class day, unless there is a test. The quiz on the first day of class will not count toward your final grade, although it may help you identify areas where you need to do some extra review work. The quiz on the day before the final is a bonus quiz. It will be different from the regular quizzes. Quizzes cannot be made up, your two lowest regular quiz scores will be dropped. In addition, your score on the bonus quiz can be used to replace a third quiz score.

The quizzes are a quick check that you have committed the concepts (and formulas) to memory. If you have done the homework exercises, and made sure that you know and understand the formulas in the highlighted boxes and the defined terms in the text (without needing to refer to the text), then you should do well on the quizzes.

Tests: There will be three tests, each covering approximately three chapters of the text. For the most part, the test questions will be like the homework exercises, not like the quiz questions. You will be asked to solve problems using the concepts and skills you have practiced. Each test will be approximately 50 minutes long, and will take place near the beginning of class. After the test, we will take our break and then resume with normal class activities.

Calculators are allowed on tests. Tests cannot be made up. In extreme situations, alternate scheduling can be arranged by contacting your instructor in advance.
