INTRODUCTION In Unit 6.1 we explored the direction and strength of relationships between quantitative variables. In this unit, we will compare and contrast several scatterplots and identify the form of the relationship between the variables. The form of a relationship between two variables provides us with information about what happens to the response (y) variable as the explanatory (x) variable changes. TRY THESE 1 In each of the scatterplots below, an explanatory variable (x) is represented on the horizontal axis and a response variable (y) is represented on the vertical axis.

A x= month number (January = 1) and y= monthly rainfall (inches) in Napa, California. (Note: Napa has several months of drought each summer.)
