This is the class, then they give us the period of the day that the class happened, and then they give us the average score on an exam. And one could, you know, we have to be a little careful with this study, maybe there's some correlation depending on what subject is taught during what period, but let's just use her data, at least just based on her data see if, see, well, definitely do what they're asking us, plot a scatter plot, and then see if there is any connection. So let's see, on the vertical, on the horizontal axis, we have period, and on this investigation, this exploration she's doing, she's trying to see, well, does the period of the day somehow drive average scores? So that's why period is on the horizontal axis, and the thing that's being, the thing that's driving is on the horizontal, the thing that's being driven is on the vertical. So let's plot each of these points. Period one, average score 93. Period one, average score 93, right over there.
