Basically for this first question there's two scenarios.
00:04
There's the positive correlation, which is right c -o -r -r because it's part of the problem, and then there's also a negative correlation.
00:17
And so basically what is happening is if you have a positive correlation what happens is as one variable increases, and it would be the independent variable, the dependent variable, i was right to keep this kind of short, dependent variable, increases as well.
00:49
And so what's different about the negative correlation is as, i'm just trying to use red, the independent variable, and sometimes we call it the explanatory variable, and then the response variable.
01:02
So if you've seen that, so maybe i'll just write that out.
01:06
Explanatory, if you saw that somewhere, variable increases.
01:16
The dependent, or the response variable, decreases.
01:27
I'll spell that out because that's the first time i spelled that word.
01:31
That's what i would write for what the correlation will show.
01:35
Some sort of connection between the two variables could be positive or negative.
01:40
So on number two, what you should notice about that r equals 0 .25, let me use a different color, is it's greater than zero...
