4.1 Evaluating Slope and Level Together

Okay, you’ve been looking at a lot of graphs, but only judging slope or level change. Now, you’ll learn how to evaluate both at the same time and practice with some graphs. Before you start judging slope and level together, we need to practice estimating the level of data paths that have an increasing or decreasing slope. It’s a little more challenging, but you still estimate the level in the same way. Imagine a band that has about half of the data points above it, and half below it.
