Course Information
Algebra I is organized around the families of functions, with special emphasis on linear and quadratic functions. Students will learn to represent them in multiple ways as verbal descriptions, equations, tables, and graphs. These functions will be applied and used to model real-world situations in order to solve arising problems. Students will also learn data analysis and apply geometric properties in the algebraic realm.

Unit 6: Descriptive Statistics
Unit Overview: In this unit you will learn how to represent data on a number line and use appropriate measures of center and spread to make conclusions about the data. You will also learn how to use scatter plots and the line of best fit to describe trends of data in real life situations. Lastly, you will learn how to use two-way frequency tables to discover associations between two-variable data.
