Unit 9 Data and Probability
Learning Outcomes
• Construct a sample space using a list, a chart, or a tree diagram to represent all possible outcomes • Predict and determine the probability of an outcome by constructing a sample space (with 24 or fewer equally likely possible outcomes) • Determine the number of possible outcomes by using the Fundamental (Basic) Counting Principle • Collect data, using observations (e.g., weather), measurement (e.g., shoe sizes), surveys (e.g., hours watching television), or experiments (e.g., plant growth) • Organize data into charts, tables, stemandleaf plots, and line plots • Interpret data by making observations and inferences from stemandleaf plots • Compare data represented in a line plot with the same data represented in a stemandleaf plot • Title the given graph or identify an appropriate title • Describe and determine the mean, median, and mode of a group of numbers representing data from a given context as measures of center • Describe mean as fair share • Describe and determine the range of a group of numbers representing data from a given context as a measure of spread 
Essential Questions
• How do you formulate a question to gain information? • How does the data you have influence the way you display it? • How do measures of center help describe the data? • How does the shape of the data help draw conclusions about the data? • How does the sample size impact the likelihood of a desired outcome? • What connections can you make between fraction concepts and probability? • In what situations would you use probability to make an informed prediction? • How can the outcomes of events be represented?
