Course Syllabus:  Winter, 2006                            back to top

Phone:  587-3810     emailglangkamp@sccd.ctc.edu              
web site: http://www.seattlecentral.edu/faculty/glangkamp/

Office:  5115        Office Hours:   M, W, F   11:00-12:40  (or by appointment)

Location: This course will meet daily from 8-8:50 in room 4166. Food is not allowed in the classroom. Drinks with lids are OK.

Prerequisites: Mat 098 with a 2.5 or better or Mat116 with 2.0 or better. Anyone not meeting these prerequisites should see me.

Note about placement:  If you met the prerequisite for this course by passing a placement test, be aware that the accuracy of such tests is fairly low. It may be the case that you were placed correctly, but perhaps you were placed either too high or too low.  If you suspect that you are in the wrong course, please come and see me ASAP, and I’ll try to help you get into the correct course.

Overload Policy: After I take attendance for 2 days, I will know how many seats are available for overload. Those students on the electronic overload list who attend the first 2 days will have highest priority for overloading the course. There is no guarantee that anyone will be overloaded into the course.

Transferring to the UW?  This course transfers as STAT220 (not STAT311 as advertised several years ago).

Materials:

a) (Required) Elementary Statistics, 9th Ed by Mario F. Triola. Publisher: Addison, Wesley, Longman. Available in the SCCC bookstore or online. If shopping online, be sure to purchase the 9th edition! Here is the web site for the text: http://www.awlonline.com/triola/

b) (Required) Course Notes, available in the SCCC Copy Center on the 3rd floor. Cost is about $3. Needed by the 3rd day of class.

c) (Required) TI-83+ or TI-84+ calculator, pencil, eraser, lined paper, graph paper, and a straightedge/ruler. Work not graded if done in ink!

d)(Recommended) Student Solutions Manual to accompany Triola's text.

Renting Calculators:   TI-83+ calculators are available to rent for $20/quarter. You will need to pay $20 to the school cashier (on the first floor), bring the receipt to me, and then fill out a contract. I will only give you a calculator if you are enrolled in the class and meet the prerequisites for the course. I will rent out calculators on Thursday January 5 in class.  

More on Calculators: A TI-83+ or TI-84+ is required for this course. This calculator is used throughout the text. Students renting calculators will have the data sets pre-loaded into their machines. Students who own a TI-83+ or TI-84+ should stop by my office during the first few days of the quarter to load the data sets into their calculators. Students who own a TI-83 (not the + model) may be able to "get by," but downloading the data sets will be more difficult. I intend to also introduce you to an online applet called StatCrunch. The applet is free to use provided you have a connection to the World Wide Web. I will also, on occasion, access other web sites to run demonstration applets.

Course Contents: This course is designed to introduce you to the basic elements of statistics: data collection and sampling, descriptive statistics, probability and probability distributions, inference, and hypothesis testing. Here is a rough guide to the weekly topics:

week 1: Intro to statistics, describing data
week 2: Measures of center, skew, and spread in data sets. Exploratory data analysis.
week 3: Z-scores, outliers, Project #1, 5 number summary.
week 4: Exam #1. Probability (brief), random variables,
week 5: Probability distributions, Binomial and normal probability distributions.
week 6: Normal and standard normal distributions
week 7: Sampling distributions, estimators, Central Limit Theorem.
week 8: Exam #2, estimating proportions, determining sample size.
week 9: Estimating means and variance. Project #2
week 10: Hypothesis Testing introduction.
week 11: Hypothesis Testing, Type I and II errors
week 12: Exam #3 Monday March 20, 8-10AM (in place of final exam).
Student work : You should expect to spend 10-15 hours per week on this course outside of class; this time will consist of reading your textbook, reading (and rewriting) your class notes, doing problems from the textbook and worksheets, working on your project, and studying for quizzes and tests. Occasionally you may need to access one of the SCCC computer labs outside of class.

Classwork and Homework: Most days you will be given a homework assignment from the text or on worksheets. There is lots of reading for this class! Keep all problems and assignments in order so that you can quickly consult them during class or at a later date. Every week or so I will collect several homework assignments from you. I will announce a few days in advance which assignments I will be collecting. Homework policies and the grading scheme are listed on the 1st page of the course notes.

Projects An important part of learning statistics is doing statistics. In this course you will have 2 projects in which you will analyze data sets, or do a statistical study.  Each will be described in more detail as the time comes. These will require group work.

Solutions to Problems: I will post solutions for most quizzes, tests, and worksheets on my bulletin board. This is located around the corner from my office (5115) by the North door to the patio. All odd numbered problems from the text have solutions in the back (the Student Solutions Manual offers more detailed explanations).

Group work: Modern educational theory suggests that students who actively engage in group discussions and problem solving sessions learn more than counterparts who do it alone. My observations from over 15 years of teaching agree with this. Therefore, I have structured this course so that there will be many activities during and outside of class in which you will have the opportunity/requirement to work in groups. You will need to make some effort to be flexible and accommodating to work out times when you can get together with your group. I also suggest that you find a study partner (or two) to work on regular textbook and worksheet assignments. Exchange phone numbers and/or email addresses!! Better yet, put your name on the Student Information Exchange for this class during the first week of class).

Tutoring Help:

1) Make use of my office hours!

2) The SCCC MATH LAB in Room 5119. This provides free, "drop in" help, and is open daily. At SCCC there is also COLLEGE WIDE TUTORING located on the 2nd floor above the latte stand: help is by appointment only but there is no charge! Unfortunately, many of the tutors in these two labs have little experience with statistics, so you might not get the fabulous help like you did when studying algebra.

3) AWL Tutoring Center: I don't know how good this is. See page xvi in the preface of our text.

Other Resources: The SCCC library's front desk has our text and student solution manual on reserve. I hope to have my SCCC web site up and running with some links to data sets, help sites, programs of study, etc. My web site is http://www.seattlecentral.edu/faculty/glangk The SCCC math faculty also has a web site with sample syllabi, course information, and cool math links. Check out http://www.sccd.ctc.edu/~ccmath/ .

Evaluation (points subject to minor changes) :

10 Homeworks

10 points each (drop the lowest score)

4 Quizzes

20 pts each, perhaps some in groups (drop the lowest score)

2 Projects

20-30 points

3 Tests

100 points each

Grades will be computed as follows: 
Grade = 0.073 times percentage correct – 2.96

(This makes 95% correct = 4.0 , 89% = 3.5, 75% = 2.5, 61% = 1.5.)

Example: In the middle of the quarter, a student has quiz scores of 20 and 22; a test score of 85, and assignment scores of 9, 10, 8, and 8.5. This is a total of 162.5 correct out of a possible 190 points.

The percentage correct is (162.5/190) x 100% = 85.5%.   The quarter grade is computed as 0.073(85.5)–2.96 = 3.3


  Policy on missing class, quizzes, tests, etc:

Special Accommodations: Students with documented disabilities who need course accommodations, have emergency medical information or require special arrangements for building evacuation should contact the instructor within the first two weeks of class.

Final Note: Information in this syllabus may be modified during the quarter.
