### Statistics and Probability

In this unit, students will build upon their previous experiences with univariate data to analyze, compare and interpret bivariate data. Students will use random sampling to generate data sets and learn about the importance of representative samples for drawing inferences. Students will investigate random processes to develop, use, and evaluate probability models. They will use lists, tables, tree diagrams and simulations to find probabilities of single and compound events. Students will use linear equations to describe bivariate data and interpret components of these mathematical models, for instance slopes and y-intercepts.

This unit was developed from the Common Core State Standards. For more information download the unit guide (on the right) where the specific content standard is identified. There may be other CCSS that align to the activities as well that are not referenced on the guide.
