Learning Outcomes

After completing this course, students should have the knowledge and skills to do the following:  

  1. Determine and interpret statistics related to the location, variability, and shape of qualitative and quantitative data sets.
  2. Apply basic concepts of probability to determine the role that probability distributions play in statistical inference.
  3. Find and interpret confidence intervals for means, variances, and proportions.   
  4. State the assumptions required for and perform basic parametric hypothesis tests about means, variances, and proportions, and find and interpret resulting p-values.  
  5. Perform basic nonparametric hypothesis tests about means.
  6. Perform linear regression and make inferences based on the results.
Apply knowledge of statistics and research design to critically evaluate research findings as well as to make more informed decisions in everyday life.


STAT 263/3.0 is a twelve week onQ-based (i.e.,online) course which presents the basic concepts and methodology of statistics with the necessary probability included. Topics include probability models, random variables, distributions, estimation, hypothesis testing, elementary nonparametric methods.

Weekly Quizzes











 Proctored Final Exam




*Whichever gives you the higher mark.

Weekly Quizzes

There will be 11 more-or-less weekly quizzes available via onQ– there is no quiz the first week and the quiz for the week of the term test is deferred into the next week. Only the highest 9 quiz marks will be used in the calculation of the quiz portion of the final grade. The questions on the quizzes will be similar to questions worked through in the lectures and presented in the non-assignments.

Midterm Exam

The term test, which covers material to the end of chapter 9, will take place during the sixth week of term. Students will take their term test online, like the quizzes. Midterm exam marks will be posted within 5 days after the midterm closes.

Final Exam

The final exam will be a three-hour formally supervised exam and will cover all the course material, with an emphasis on material from the second half of the course. This is so because much of the material covered in the first half of the course is fundamental to the material covered in the second half. Details about the final exam will be posted as they become available.

Students must write their exam on the day and time scheduled by the University. The start time may vary slightly depending on the off-campus exam centre. Do not schedule vacations, appointments, etc., during the exam period.
