2.7 Curve fitting
Fit scatterplot data and use linear models to make predictions
A Regression is a relationship between the variables
A scatter plot is a graph of order pairs.
Main purpose is to analysis a relationship between the two variables
Strength is classified by a Correlation
A line of best fit is use to make a prediction.

What is Lebron James’ shoes size ?
6' 8"
What is Lebron James’ shoes size if he is 6 ft 8 inches? In order to find out we will (1) gather all students’ height / shoe sizes. (2) Make a scatter plot. (3) Look for any correlation. (4) Draw a line of best fit. (5) Find equation of our line. (6) Use the line to make a prediction.
