Final marks: The final marks have now been computed, and should shortly be available from ROSI. Marks for the mid-term, the assignments, and the final exam are available here. Please let me know of any errors.
You can come by my office to pick up your second assignment. I'm around most afternoons; you can phone at 416-978-4970 if you want to check if I'm in.
You can now look at an example solution to assignment two.
The main topics of this course are: (1) How meaningful data can be gathered, and presented in a way that allows one to make intuitive sense of it. (2) The basics of probability, and how it is used in more formal procedures that help distinguish real patterns in data from coincidences. (3) Some fundamental statistical techniques, including t tests, linear regression models, one-way ANOVA, and analysis of contingency tables. Students will learn the theory behind these concepts (at a moderate mathematical level), and will obtain experience in apply them using the Minitab computer package.
Please read the important information on course policies.

Assignments will be done using the Minitab statistical package on the CQUEST computer system. Your CQUEST account should be posted across from SS 2133, near the terminal room in SS2105.
Here is the CQUEST page for STA 250.
It is also possible to buy Minitab for use on a home computer, but you should not expect any help in installing it.
Grading Scheme: Assignment 1: 17%, Mid-term test: 20%, Assignment 2: 17%, Final exam: 46%
Scheduled by the Faculty of Arts and Science
The final exam will cover the whole course, though there will be more questions on material after the midterm test than before.
No books or notes will be allowed. You may use a calculator. You can write in pencil.
You won't be expected to remember any really complicated formulas. The most complicated one that might be needed is the formula for the t statistic for a two-sample t test. All the formulas you will need should be easy to remember if you understand the concepts involved.
Here are the questions: postscript, PDF.
Here are the answers for Questions 1-41 (along with a few comments) and the answer to Question 42 (with marking scheme).
The mark is out of 100 (87 for Questions 1-41, 13 for Question 42).
The mark written on the answer sheet will be adjusted upward by 4.
The median of the adjusted marks was 67.
