Stage 1 – Desired Results Established Goals: Students will use experimental or theoretical probabilities to represent and solve problems involving uncertainty. Students will also collect, display and analyze data to solve problems. Understandings: Essential Questions: Students will understand that… -What is theoretical probability? -probability plays an important role in -What is experimental probability? decision making. -What is subjective judgment? -data collection can be influenced be many -What affects data collection? different factors. -How do you choose between a population and a -data collection about a sample will produce sample? valid results about the population if the -How do you choose an appropriate sample? sample is representative of the population. Knowledge: Skills: Students will know that… Students will… -decisions may be based on theoretical or -explain how probability is used outside of the experimental probability, subjective judgment classroom. or a combo of these -describe how the collection of data may be -probabilities are based on assumptions. adversely affected. -probabilities can be used to support -select and defend the choice of using a opposing views. population or a sample. -data collection can be affected by; bias, -search a Canadian database for information, use of language, timing, privacy, cultural then make comparisons. sensitivity, ethics, cost and time -understand and choose an appropriate sample. -in a census, data are collected from each -display data on graphs using spreadsheets. member of the population. -develop a project plan. -when it is unreasonable to conduct a census, data is collected from a sample of the population. -when a sample is representative of the population, the data collected from the sample leads to valid conclusions. -online databases can be used to find statistical information. -spreadsheet software can be used to record and graph data. -there are many different ways to select a sample. -random samples are most likely to produce valid conclusions.
