It shows two manipulated variables, which are supp for the vitamin C supplement, it either uses vitamin C or orange juice. And the dosage, which is 500, 1000, or 2000 milligrams, I assume, and how it affects the length of tooth growth in guinea pigs. The idea here is that vitamin C is good for tooth growth. And so let's take a look at how these variables, these two factors each affect the length of tooth growth along with their interaction between the two. To do this we come up…
