Required Text Introductory Statistics second edition  by Jay Devore / Roxy Peck

Course description This course will cover analysis of data including probability, distributions, sampling, hypothesis testing, confidence intervals, regression analysis, and ANOVA.

Prerequisite A grade of C or better in Math 154 or an equivalent class within the past two years, or a satisfactory score on the assessment test.

Grading Policy Your letter grade will be based on your percentage of possible points.

A 90 -- 100% C 70 -- 79%

B 80 -- 89% D 60 -- 69%

Homework: ...........................................100 points

Midterm 1: Jan 26 .................................150 points

Midterm 2: Feb 14 ................................150 point

Midterm 3: Mar 15 ................................150 points 

Project: Mar 13 .....................................150 points

Final Exam: Mar 20................................300 points

Exam Policy Students are to bring calculators, pencils or pens, and paper to each exam. A one page (standard size) front and back formula sheet may be used during each midterm, and a two page formula sheet may be used during the final exam. Grading will based on the progress towards the final answer, and the demonstration of understanding of the concept that is being tested, therefore, work must be shown in detail. Any student who cannot make it to an exam may elect to take the exam up to two days before the exam is scheduled. If all homework assignments are turned in for the quarter, and no more than three assignments are late, then the midterm with the lowest score will be dropped.

Homework Policy The use of computers or calculators is strongly recommended. Also, feel free to consult a fellow classmate, a tutor, your instructor, or anyone else for assistance on the homework.   Homework that is turned in within one week of the due date will be counted as half credit. Homework may be turned later than one week after the due date, but points will not be awarded.

Extra Credit Any student who has turned in every homework assignment may elect to work on an extra credit assignment or project that will count as additional points towards either a midterm or the final.

Project Each student in the class will develop a hypothesis that involves paired data. A group of several students will individually collect data to test the hypothesis. A report will be turned in that discusses the results of the test, the method of the test, and the validity of the test. The report must be more than two pages not including raw data and graphs.  Included in the report will be all applicable methods of data interpretation that we have learned in class. More details will be given in class.

Registration

1. You must register for this class at the Office of Admissions and Records.

2. You may drop the class with no penalty or mark on your record on or before Friday, January 28.

3. After January 28, you may drop the class and receive a grade of W until Friday, March 3.

4. After March 3, if you are enrolled, you will receive one of the following grades:  A,B,C,D,F or I (Incomplete, must be negotiated with the instructor and is only allowed in special cases).

HOW TO SUCCEED IN A MATH CLASS

  1.  Come to every class meeting.
  2.  Arrive early, get yourself settled, spend a few minutes looking at your notes from the previous class meeting, and have   you materials ready when class starts.
  3.  Read each section before it is discussed in class
  4.  Do some math every day.
  5.  Start preparing for the tests at least a week in advance.
  6.  Spend about half of your study time working with your classmates.
  7.  Take advantage of tutors and office hours, extra help can make a big difference.
