Solutions to today's Quiz 2 have been posted above in the "solutions" section.

Material covered in class:

  • Complement of an event
  • General addition formula for probability


30 JANUARY 2017 (Lecture 2.1) announcements:
QUIZ 2 is this Wednesday! It will cover all material covered to date, excluding what was covered in today's class (intro to probability).

Material covered in class:

  • The r-score (continued)
  • Intro to elementary probability theory, definitions and examples of: sets, union of sets, intersection of sets, the empty set, disjoint sets, probability (classical and frequentist interpretations), sample spaces


25 JANUARY 2017 (Lecture 1.2) announcements:
Solutions to today's quiz have been posted above in the "solutions" section. For those students who did not get full marks on question 1 (using the calculator to compute the mean and standard deviation), you can earn back up to half of the marks by demonstrating the calculations to me after class on Monday. So, you all have 4 more days to learn how to use your calculator!

Material covered in class:

  • Statistical terminology for samples and populations
  • Population parameters vs sample statistics
  • The z-score
  • The r-score as an example of the use of z-scores


23 JANUARY 2017 (Lecture 1.1) announcements:
QUIZ 1 is on Wednesday! It will cover means, medians, variance and standard deviation. You should know how to compute these things using your calculator.

Material covered in class:

  • Mean, median, sample variance, sample standard deviation
  • Discussion of advantages and disadvantages of the mean and median
  • Using your calculator to compute mean, sample standard deviation and sample variance


18 JANUARY 2017 announcements:
Please bring your calculator to next Monday's class. If you do not have the recommended calculator (Sharp EL-531XG, available at the Dawson Bookstore) please bring along your calculator model's instruction manual (which you can find easily online).

Material covered in class:

  • Presentation of course outline parts I and II (see above under "downloadable stuff")
  • Stat Fact of the Week: Simpson's Paradox (watch a video here: Simpson's Paradox explanatory video)


10 JANUARY 2017 announcements:
Welcome to your Statistics Class! You will find all material related to the course on this website, including a PDF version of your textbook, a reference textbook, solutions to your tests and quizzes and a summary of what was covered in class. Please check the website every few days to keep abreast of what's happening in the class.
