#### Objectives

- Students will understand how various data transformations can be used to achieve a linear relationship and, consequently, how to use the methods of linear regression to obtain a line of best fit.
- Students will use various calculator regression functions in order to model the relationship between two variables.
- Students will convert a linear regression equation back to a non-linear equation to model the relationship between two variables.

#### Vocabulary

• transformation

• linear regression

• exponential regression

• power regression

• logarithmic regression

#### About the Lesson

This lesson involves three real-world data sets in which the relationship between each pair of variables is non-linear.

As a result, students will:

- Learn how data transformations may be used to achieve a linear relationship.
- Learn how to use several calculator regression functions to model the relationship between two variables.
- Learn how to convert a linear regression equation back to a non-linear equation.
