Back

A positive association indicates that as one variable increases, the other variable also tends to increase.

What is a linear relationship in a scatter plot?

Back

A linear relationship is when the points in a scatter plot form a straight line, indicating a consistent rate of change between the variables.

Front

What is a nonlinear relationship in a scatter plot?

Back

A nonlinear relationship is when the points in a scatter plot do not form a straight line, indicating that the rate of change between the variables is not constant.

Front

How can you identify a positive linear association in a scatter plot?

Back

A positive linear association can be identified when the points slope upwards from left to right.

Front

How can you identify a negative linear association in a scatter plot?

Back

A negative linear association can be identified when the points slope downwards from left to right.

Front

What is the purpose of a scatter plot?

Back

The purpose of a scatter plot is to visually represent the relationship between two quantitative variables.
