How can you determine the strength of a relationship in a scatterplot?

Back

The strength of a relationship can be determined by how closely the points cluster around a line; a tighter cluster indicates a stronger relationship.

What is a linear relationship in a scatterplot?

Back

A linear relationship is one where the data points can be approximated by a straight line.
