 level. It's the level at which the behavior is occurring, or the intensity, or whatever it is, right? So if you have a graph, which see the video I'm graphing, I don't care if it's a bar graph, or a line graph, whoa, the level's not getting very level anymore. So anyway, so if you have a level, it is how far up the thing is on the y-axis, really, that's all there is to it. So that level here is at a fairly high level if you had an axis like this sort of thing, it's way up there. But it's like off the top of it's, I don't know, it's rocking. It's not level anymore. So which kind of level do you want? I want a level level. So anyway, sorry folks, it's really simple. So we had to do something really stupid and funny. So a level, not that kind of level. It's the level of behavior. That's the level of the dependent variable, which is dependent upon the independent variable. See the other videos, please.
