Quiz tomorrow--5 min! "Is a linear model appropriate?" and "Find the equation of the LSRL using your calculator." After grading/stamping your stamp problems from today, here are a few pointers....
- Remember you're looking for random scatter in the RESIDUAL plot, not the scatter plot
- When you explain your reasoning, make sure you say there is/isn't a pattern in the RESIDUAL plot. Be specific.
- Draw the residual plot!
- Don't forget the other two conditions!
- Look at the scatter plot (L1 vs. L2 most likely) for outliers.
- Don't just say "the variables are quantitative." You have to tell me what the variables are!
