A friend of mine teaches in Northwestern Ontario and maintains a YouTube channel of math videos. He has them organized on the following page for Data Management:
Your Math Videos: Data Management
We’re working on the same content as is in his Unit 3 section (Combinations). I recommend watching his stuff for extra examples, another explanation, and some more practice (with a ‘C’, eh?).
We started working with playing cards today. Your home is this question:
You deal 5 cards from a deck of 52 cards, 1 card to each of 5 people. How many different unique arrangements are there that include all 4 queens?
Since all four queens are included, there are only 48 cards left to choose from for the fifth card. There are 5! ways to arrange the five cards, so this means there are (48)(5!) = 5760 total arrangements.
Here’s the booklet we’ll be working on today, in preparation for tomorrow’s test. (You also have your review questions if you haven’t finished them.)
Skills Tracking – Introductory Statistics – booklet
Here’s what we’ve been working on this week:
Our task was to compare each pair of quantitative variables (for example, compare population with police expenditure) using scatter plots, lines of best fit, and the correlation coefficient.

I won’t be there today – I’m working with other math teachers to improve my teaching (which you’ll hopefully enjoy the benefits of).
While I’m gone you’ll be doing a couple of things.
- Watch the video below (twice, if you want to).
- Work at your half-table groups (move around if you like) to design three experiments using what you learned (here’s the handout you’ll use).
- Share your experimental designs with the entire class.
That’s it for today! No homework for the weekend. Next week we’re going to be spending time using spreadsheets some more, and we’ll move towards wrapping up this first unit in the course with some review stuff.
