Welcome to Statistics 12!
Hi, I'm Lawron, and this is a supplemental resource that will help you complete your grade 12 stats course.

This resource includes the following activities: 
   Theory lessons: I will explain and summarize new data and stats concepts
   Examples: I will walk you through how to solve problems involving these new data and stats concepts
   Practice questions: These are for you to try out on your own. Don't worry, if you get stuck, you can watch the video solutions or read the suggested written answers

You may notice the word "(Bonus)" in some of the section titles. These indicate topics that some teachers may choose to teach, but is not necessarily a part of the provincial curriculum. I decided to include these topics in this resource because they are important for you to know if you choose to take higher level statistics.

Feel free to go through this resource at your own pace
