Statistics 224: Introductory Statistics for Engineers

Check www.stat.wisc.edu/~jgillett/224 for updates to this tentative syllabus.

Goals
You will understand statistical concepts and methods including collecting, describing, and displaying data; fitting a line to data; probability, random variables, and probability distributions; random sampling and sampling distributions; inference about means and proportions, including confidence intervals and hypothesis tests; factorial experiments; and statistical quality control.

You will be a critical reader of statistical claims.

Textbook
Principles of Statistics for Engineers and Scientists by William Navidi (ISBN-13: 9780077289317). (A cheaper electronic version is at www.CourseSmart.com.)

Computing
A scientific calculator is required for exams and homework. Here are instructions for some common calculators. A computer is required for homework. If you have a laptop, bringing it to discussion will be helpful on days that TAs discuss OpenOffice Calc (a free version of Excel).

Help
The TAs and I are eager to help in class and office hours. Free tutors are available daily in MSC 1586: see www.stat.wisc.edu/courses/Tutorial_Schedule.

Grades
About 700 points are available on two midterm exams (150 each), a final exam (200), homework (112), and online quizzes (88). I'll assign grades according to the percentage scale, A = [92,100], AB = [88,92), B = [82,88), BC = [78,82), C = [70,78), D = [60,70), F = [0,60) (92% of points => A); and according to the percentile scale, A = 70, AB = 60, B = 45, BC = 30, C = 10, D = 5, F = 0 (performing better than 70% of the class => A). Your grade will be the higher of these two grades.

Homework and online quizzes will usually be due Fridays at the start of lecture. I'll post them in the schedule, below, a week before they're due. Write your name, discussion number, and TA on the first page of homework. Show your work. Homework must be easily legible, with pages joined by a staple. Homework is graded on this scale:
8/8almost all correct, with adequate work shown
6/8pretty good
4/8incomplete, or a lot wrong, or inadequate work shown
0/8not turned in or some other big problem

If you anticipate religious or other conflicts with course requirements, or if you require accomodation due to disability, you must notify me during the first three weeks of class. You may not make up missed homework or exams, except in the rare case of a documented, serious problem beyond your control. (Well, there's an exception: if you give me late homework in person before I leave on Friday, which is usually around 2:30, I'll accept it with a 25% late penalty.)

I encourage you to discuss the course with others, but you must write homework, quizzes, and exams by yourself and prevent others from copying your work. (See the UW Academic Misconduct policy.)

Lecture notes
I'll post lecture notes a week at a time by changing book section numbers (like "1.1") in the schedule, below, to links.
