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.
