Correct your own work and redo missed problems.
(You book marked “selected answers” in week 0. You’re usually looking at the selected answers for Practice Problems.) Remember to:
Mark correct problems with a little colored dot so you and I know that you have checked them against the answer.
Mark problems you missed with slash in color.
Redo the problem in the right-hand column and check your work again.
If you still don’t get it, make a note of that problem so we can review these
Then use the HW self-assessment form (see button up top) to self-assess your work.
Preview or Review:
In previous math classes, you probably learned how to make a scatterplot. Review the directions on McD page 48. Here’s a video if you need extra review: https://www.youtube.com/watch?v=hKNFn2E2biw
