Back

A linear association is a relationship between two variables that can be represented by a straight line on a scatterplot.

What is a nonlinear association?

Back

A nonlinear association is a relationship between two variables that cannot be represented by a straight line; the relationship may curve or change direction.

Front

How can you identify a positive linear association in a scatterplot?

Back

A positive linear association is identified by data points that trend upwards from left to right, forming a straight line.

Front

How can you identify a negative linear association in a scatterplot?

Back

A negative linear association is identified by data points that trend downwards from left to right, forming a straight line.

Front

What is the purpose of using scatterplots in data analysis?

Back
