Chicken Pox in the United States x y # of years after 1988 Chicken Pox in the U.S.A. YearCases (Thousands) Reported cases (1000’s) Draw a Scatter Plot of the data. 2.5 Correlation & Best-Fitting lines OBJ: to Use a scatter plot to identify the correlation shown by a set of data & Approximate the best-fitting line

x y x y x y positive correlation negative correlation no reliable correlation Describe the Correlation shown.

Draw the Best-Fitting Line *most closely follows the pattern/ as many point above the line as below it

Example 1 Create a scatter plot for the data shown below. Describe the correlation. Then find and graph an equation for the best-fit line. x y

Correlation and Prediction: x y perfect positive correlation x y no reliable correlation r =0 r =1
