## MAthematics 9 probability and Statistics

**Specific Curriculum Outcomes**

**SP01**

**Students will be expected to describe the effect on the collection of data of bias, use of language, ethics, cost, time and timing, privacy, and cultural sensitivity.**

**SP02**

**Students will be expected to select and defend the choice of using either a population or a sample of a population to answer a question.**

**SP03**

**Students will be expected to develop and implement a project plan for the collection, display, and analysis of data by: formulating a question for investigation; choosing a data collection method that includes social considerations; selecting a population or a sample; collecting the data; displaying the collected data in an appropriate manner; drawing conclusions to answer the question.**

**SP04**Students will be expected to demonstrate an understanding of the role of probability in society.

## SP01 activities

**Backpack Survey Activity**- Imaging giving a survey to every grade 9 student at school and asking them what colour their backpack is (population). How might the results look different if we gave the survey to just the students in your math class (random sample)? How might this change if we gave the survey to just female students in the cafeteria at lunchtime (biased sample)?

## SP02 Activities

**Sampling and Estimating: Counting Trees from the Mathematics Assessment Project**- Students attempt to count the number of young an old trees in a tree farm. They learn how to use sampling techniques to establish a good estimate of the actual number.

**Learning Sampling with Candy**- Students learn about sampling populations using some easy to understand activities.

**Capture-Recapture with Goldfish Activity**- Students use sampling techniques to estimate the total number of goldfish in their pond. Another teacher also recorded their experience with this activity.

## SP04 Activities

- Ask students to think of a TV game show where players consider probabilities when deciding how to proceed, and then explain the extent to which probability is involved. All the stats for games from The Price is Right are collected online. Games that could be played in class and analyzed include Master key
