SCATTER PLOT GRAPHING

Definition: A graph in which two sets of data are plotted as ordered pairs in a coordinate plane.

Used to find the relationship between multiple sets of data.

Numerical data is used.

INTRODUCTION

1. Collect data as ordered pair2. Make graph and plot points3. Determine the correlation/relationship

(positive, negative, or none)

There’s a positive correlation which means the years of experience does affect the amount of homeruns hit.

PROBLEM/MEANING

They can be used to display large amounts of data.

Easy to analyze relationships between two quantities.

Easy to predict what is coming next in data.

ADVANTAGES

Can be hard to read because of overplotting.

Takes a long time to graph.Hard to tell where exactly a point is

placed if it’s not on an intersection.
