Scatter Plot Graphing

By: Julia Garcia

Juliana Bove

Kelli Koenig

Period 5


Introduction

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

Explanation

  • Collect data as ordered pair

  • Make graph and plot points

  • Determine the correlation/relationship

    (positive, negative, or none)


Constructed example

Constructed Example

  • Social Media Apps and Sleep


Problem meaning

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

Real-Life Graph

  • Babe Ruth’s Homeruns


Problem meaning1

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.


Advantages

Advantages

  • 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.


Disadvantages

disadvantages

  • 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.
