Finding Linear Models

Activity Overview

Students graph a scatter plot, find average rate of change, develop a linear model, find a linear regression and a median/median line for a set of data graphed in a scatter plot, and predict profit.

Before the Activity

Students graph a scatter plot, find average rate of change, develop a linear model, find a linear regression and a median/median line for a set of data graphed in a scatter plot, and predict profit.

During the Activity

Part I. Enter data into lists, determine an appropriate window, and graph a scatter plot. Part II. Find average rate of change and intuitively develop a linear model for a set of data graphed in a scatter plot. Part III. Find a linear regression and a median/median line for a set of data graphed in a scatter plot. Use models to predict profit.

After the Activity

  • Review student answers
  • As a class, discuss questions that appeared to be more challenging
