checkpooint 3: completed scatterplot
I think i am used to bottom-up problem solving. I like doing problems by first utilizing the knowledge I already have and expanding it. Top-down thinking, like we did in checkpoint 1 may sometimes make it difficult to proceed once you get stuck in a step. For bottom up, you can move onto a different part which you already know.
