## What do contour plots show?

Contour plots (sometimes called Level Plots) are a way to show a three-dimensional surface on a two-dimensional plane.

It graphs two predictor variables X Y on the y-axis and a response variable Z as contours.

These contours are sometimes called z-slices or iso-response values..
