Back

It indicates a strong relationship between the variables, with a larger change in the dependent variable for a change in the independent variable.

Front

What does it mean if a line of best fit is flat?

Back

It indicates a weak relationship between the variables, with little change in the dependent variable for a change in the independent variable.
