Ran in 3 of the last 7 terms. Winter 2027: not on the schedule. Spring 2027: schedule not out yet.
A first of a two-course sequence that introduces fundamental concepts in probability and statistics. It covers probability concepts, random variables, graphical display of distributions and data, discrete and continuous probability distributions, sampling, estimation, confidence intervals, experimental design, hypothesis testing, and simple linear regression and correlation. Students learn how to graphically explore data, conduct, and analyze a two-treatment experiment, and model data with linear regression, and interpret its fit. Students learn to use statistical computing software (e.g., R) to perform data analyses. Emphasis is placed on gaining experience with data collected from student-conducted experiments.

I enjoyed this course and think it was a good introduction to probability and statistics. I had Fatih Safa Erenay as a prof. I enjoyed the lecutes and he kept them engaging, although sometimes he would go slightly 'off script' and make up examples/derive things on the spot which often just led to the class being more confused. I wish the course had weekly assignments or more involved lab assignment though to help get more practice in throughout the term. Exams were fair and reasonable.

Focus on this course in 2A.

This is essentially AP Statistics minus a few topics. Lots of connections to MDM4U (Data Management) in the Ontario High School curriculum, so if you still remember those concepts, you'll do well in this course. Reasonable course load, knowledge-type MCQ short quizzes, application-type assignments (with tutorial questions that cover very similar questions), and labs focused on R and visualization. Final examination was fair and mostly MCQ (lack of practice questions though). Feedback is fast, it only takes a week. Easy to do well if you put in the effort
