The purpose of this unit is to introduce and reinforce the concept of probability and how it plays into the larger concepts of data analysis and statistics. Students will need to understand the general concept of probability, as well as the coordinating concepts of combinations, permutations, and independent and dependent events. All of these concepts are selected based on both the Tennessee State Standards and the Common Core State Standards. Prior to this unit, students will have a working knowledge of probability, having been introduces to the concept in middle school. Also, students will have been taught a basic understanding of independent and dependent events. This unit will serve to reinforce the concept in contextual settings, working students toward mastery and understanding of the real-world applications of data analysis. In order for students to be able to participate in the planned activities, they will need to have a working knowledge of probability, including the difference between theoretical and experimental probability and the methods of calculating each. Remediation and reteaching will be provided for those students who struggle to master the content.
