The course is an introduction to statistics. Students are introduced to the notions of graphical and descriptive methods in statistics, probability models, random variables and distributions, sampling, estimation, hypothesis testing, regression, analysis of variance, exploratory and diagnostic methods, statistical computing.

Here are some background notes on set theory: brief note, longer article (by Daniel Ashlock at University of Guelph).

The only way to understand and master the material presented in class is by working out the homework problems on your own. You are strongly encouraged to work out the homework problems that are assigned regularly and carefully. Copying the homework from someone else or watching someone else doing the work for you will bring you minimal benefit. The homework will count 30% towards the final grade. There will be (almost) weekly homework assignments posted at the link below. At the end of the semester, your worst HW score will be dropped.

Homework submission and evaluation policy: Every week I will collect the homework and administer a short quiz (10 min) based on the homework. The quiz will be at the beginning of the lecture and the homework is due on the DUE DATE AT THE BEGINNING OF THE LECTURE (12:05PM). Your homework score will be determined by the combination of quiz score (80%) and collected assignment (20%). No late homework submissions will be accepted. A late or missed HW will receive a 0 score. Homework should be submitted in a "professional" form which allows a grader to read your solutions without unnecessary effort or ambiguity. In particular, your solution should either be typed or handwritten in a neat and legible form; if you submit scanned pages, they should be perfectly legible; submitted pages should be ordered with clear indication of which problem is being solved; if your homework solution consists of more than one page, pages must be stapled. Collected homework which does not satisfy these guidelines might receive up to a 50% penalty in the score.

Tests. There will be three tests in class counting 40% towards the final grade (tentatively) on WED FEB 17, WED MAR 23, MON APR 18 . The worst of your 3 tests will be half-dropped; that is, the 3 tests counts 40% towards the final grade, where the best two tests will count 16% each, the worst one will count 8%.
Final exam. The final exam counts 30% towards the final grade. This is scheduled on FRI MAY 6 at 11 am.
Makeup test. Makeup tests will be allowed only for justified and unavoidable absences. In this case, if possible, previous authorization should be obtained from the Instructor. In all other cases, you will get a zero score for a missed test.

Here are some old tests with solutions:
Test #1 - Solution -- Test #2 - Solution -- Test #3 - Solution.

Here are the tests with solutions: (I will post the information for current tests when available)
Test #1 with Solution -- Test #2 with Solution -- Test #3 with Solution

 

The grade will be determined according to a set point scale: 90%-100%: A, 80%-89%: B, 70%-79%: C, 60-69% D; F is less than 60% (+ and - will also be used).
