Scatter Plots

January 19th Asynchronous Lesson

A scatter plot is a graph that is used to show data between two variables, also known as bivariate data.

• ​For ex: height and weight.​

​

Scatter plots show patterns, trends, and associations between variables that could impact each other.​

Scatter Plots

​Positive Association	​Negative Association	​No Association
​Both variables are increasing.	One variable is increasing, the other is decreasing.​	There is no relationship between the variables.​
