3.15 Third Step in Estimating Slope with Variable Data

We’ll then adjust the angle of our original blue slope line so that it’s as parallel as we can get it to our top and bottom lines. This is similar to how we adjusted the level band up or down to fit the data, but because we’re talking about the slope, we need to change how the line is angled or tilted. When we do this, we can see that this data path has an increasing slope. In general, even though there is some variability in her accuracy, the girl is performing more of the steps of making a sandwich independently each day.
