Today Joshua was out so we met on Teams. We watched a short video together about residuals. Ironically, this is something Joshua was already familiar with, but I have never actually seen it before. So I learned along with him and he explained to me what he already knew. We used the calculator to enter in data and it gave us a linear regression model. Then we used that function to determine how far apart the actual data is from the predictive model. Then we calculated the percent error.
