1. Scatter Plots

2. Graphing Basics Coordinate Plane – Two real number lines that intersect at a right angle.

3. Graphing Basics Ordered Pair – Each point located on the coordinate plane. (x,y) x-coordinate – The first number in the ordered pair. (5,-3) y-coordinate – The second number in the ordered pair. (5,-3) The point in the plane that corresponds to an ordered pair (x,y) is called the graph of (x,y)

4. Scatter Plot Scatter Plot – A collection of ordered pairs graphed onto a plane Usefulness? –Show a “correlation” between the values of x and the values of y. –Able to be made quickly

5. Correlation Positive Correlation

6. Correlation Negative Correlation

7. Correlation No Correlation
