3.5.1 • Using Bivariate Data in Context

Warm Up

In the following activity, you will complete a series of questions regarding scatter plots and the variables that represent the data.

Examine the unlabeled graphs below, then match the variables to the scatter plot you think they best fit. Choose from among the following variable combinations. Be prepared to explain your reasoning.

x x variable = average number of free throws shot in a season
 y y variable = basketball team score per game
x x variable = daily low temperature in Celsius for Denver, CO
 y y variable = boxes of cereal in stock at a grocery in Miami, FL
x x variable = measured student height in feet
 y y variable = measured student height in inches
x x variable = average number of minutes spent in a waiting room
 y y variable = hospital satisfaction rating
