Course Description

A study of both descriptive and inferential statistics. Topics for the course include: data presentation, and analysis, measures of central tendency and dispersion, sampling distributions, parameter estimation hypothesis testing, and linear regression. Prerequisite: Grade of "C-" or higher in MATH 95 or permission of the Mathematics Department.

Required Materials

1. The required textbook for the course is Intro Stats, 1st edition, De Veaux and Velleman, published by Pearson/Addison Wesley, ISBN 0-321-21178-2. This version of the textbook is bundled with an access code to supporting online materials via the URL http://students.pearsoned.com/.

Access to the online resources is required for submission of graded homework for both the lecture section and online section of Math 201. The online resources include not only homework assignments but also contain an electronic version of the entire text (in pdf form), the complete Student Solution manual (in pdf form), sample chapter tests with electronic grading, and discussion boards.

If a student is comfortable using only electronic resources for the course it is possible to purchase a standalone access code to the online Math 201 materials without a printed textbook for $30 (go to either the WWCC Bookstore for an access code or go to http://students.pearsoned.com/ for information about purchasing just the website access code). Once registered at http://students.pearsoned.com/ the complete text can be read on screen using Adobe Acrobat's Reader (each chapter is its own pdf file). Keep in mind that working entirely with an electronic form of the text is not for everybody and can present some challenges of its own in addition to the subject matter of the course; however, there are some students who are very comfortable with electronic texts and may choose to acquire the text in this manner. In this course the students have a choice whether to purchase and use a printed text and use the electronic form as a supplement or use only the electronic form.

If a student purchases a used text it will be necessary to purchase an access code to the web materials from either the WWCC Bookstore or the online at http://students.pearsoned.com/

To complete the website registration at http://students.pearsoned.com/ requires (1) a valid email address, (2) course ID which is schulz69411, and (3) a valid access code (either bundled with the text or purchased seperately). All WWCC students are provided with an email address while enrolled at WWCC that can be used as a valid email address - see http://www.wwcc.edu/kiosk/ for information about your student email account. I will be sending emails out regularly to students regarding course material and information - be sure to use an email address that you check regularly when registering for the online materials at http://students.pearsoned.com/

2. A scientific calculator with basic statistical functions will be necessary. There are many different calculators that are sufficient for the needs of the course. Please feel free to contact the instructor with any questions about calculators.

3. Bookmark the course website http://math.wwcc.edu/eric/math201/ and check the homepage regularly for notices, announcements, etc. It is important to check the Quarter Schedule regularly as well as the schedule for the course may be modified as the quarter progresses.

Attendance - Lecture course

Attendance at every class session is expected. I understand absences are sometimes unavoidable and will work with students when such occasioins arise. In the event of an absence occuring on the date of a scheduled exam, prior arrangments must be made in order to schedule a time to write the exam.

Lecture notes will usually be posted after each class session as pdf files. See the quarter schedule for links to the daily lecture notes. The posted notes do not take the place of student taken notes - they are meant to be used as supplements to those notes taken by students in class.

Homework

Homework will be assigned regularly from the textbook and discussed in class; additionally, questions on the assigned homework can be posted to the Discussion Boards at http://students.pearsoned.com/ where other students as well as the instructor will be able to respond. "Finish By" dates are listed on the quarter schedule for each textbook assignment. The Discussion Boards for the course material are found in the Communication link visible after logging into http://students.pearsoned.com/. In the Course Information area of the website http://students.pearsoned.com/ you will find a Student's Solutions Manual giving detailed solutions to every other odd problem. The problems from the textbook should be completed before working on the online assignment - this will ensure the online problems will be completed quickly.

The textbook assignments will not be turned in for grading; graded homework will be completed and graded using online resources at http://students.pearsoned.com/. Problems very similar to those assigned from the textbook have been assigned at http://students.pearsoned.com/ and are to be completed online and will be graded by the online tools. Due dates for each online chapter assignment are listed on the quarter schedule. The due dates for each online assignment are "hard" in that completed solutions must be submittted by midnight on the due date. Working only the online problems is likely not sufficient to gain mastery of the course material.

To complete the homework assignments at http://students.pearsoned.com/ you must first register using your email address, courseID, and access code. Once registered go to http://students.pearsoned.com/ to log in.

Do not hesitate to contact your instructor if problems are encountered.

Exams

The four one-hour exams and final exam are traditional paper and pencil exams on which a scientific or graphing calculator is allowed (and expected to be used). The students enrolled in the lecture section will take each exam on the date specified on the quarter schedule in Room 207. Students enrolled in the online section will need to take the exams in a prearranged proctered setting within one weekday of the date on which the exam has been scheduled according to the quarter schedule - either one weekday earlier, the day scheduled, or one weekday later which provides a three day window for each exam. It is permissible to bring a 3"x5" card to the exam with formulas/notes written on it provided the card is turned in with the exam.

Students enrolled in the online section need to make arrangements for proctored exams and notify the instructor well in advance of the scheduled exam. A description of the proctored environment should be included as well so that it may be determined to be "appropriate" - quiet, closely monitored, etc. At the Walla Walla campus there is a new Testing Center in which the exams should be scheduled. The hours for the new Testing Center in Walla Walla will be posted on the course website.

If a student cannot take an exam as scheduled, an alternate date must be arranged with the instructor prior to when the exam is scheduled.

Course Grades

Points earned on the homework assignments completed using http://students.pearsoned.com/ will be scaled to 100 points using the formula

hw = 100*(homework average %)

There will be a total of 4 one-hour exams worth 100 points each (ex1, ex2, ex3, ex4) and a comprehensive final exam (fx) worth 150 points.

The course percentage (cp) upon which grades will be determined is computed with the function:

cp = ( hw + ex1 + ex2 + ex3 + ex4 + fx - minimum(ex1,ex2,ex3,ex4) ) / 550

The letter course grade earned by the student is determined by the following table:

93% <= cp<=100%
-> A
90% <= cp <93%
-> A-
87% <= cp <90%
-> B+
83% <= cp < 87%
-> B
80% <= cp < 83%
-> B-
77% <= cp < 80%
-> C+
73% <= cp < 77%
-> C
70% <= cp < 73%
-> C-
67% <= cp < 70%
-> D+
60% <= cp < 67%
-> D
0% <= cp < 60%
-> F
