What does a positive linear relationship look like in a scatterplot?

Back

In a positive linear relationship, as one variable increases, the other variable also increases, resulting in a line that slopes upwards.

Front

What does a negative linear relationship look like in a scatterplot?

Back

In a negative linear relationship, as one variable increases, the other variable decreases, resulting in a line that slopes downwards.
