Period 5

### Introduction

• 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.

### Explanation

• Collect data as ordered pair

• Make graph and plot points

• Determine the correlation/relationship

(positive, negative, or none)

### Constructed Example

• Social Media Apps and Sleep

### Problem/Meaning

• Does the amount of social media apps on your phone or iPod effect the average amount of sleep you get?

• There is no correlation between the two variables, so they don’t affect one another.

### Real-Life Graph

• Babe Ruth’s Homeruns

### Problem/Meaning

• Do years of experience effect the amount of homeruns Babe Ruth scored in baseball from 1918 to 1927?

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

• 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.

• 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.
