Hi everybody.
00:05
So today we're going to be going through problem number nine in chapter two, the research enterprise and psychology.
00:11
And this question is asking us about correlation.
00:13
So i'm going to write that down here.
00:17
So we know that a correlation is essentially an association between two different variables.
00:23
So i'm going to write that down here.
00:26
Correlation is an association between two variables.
00:36
Now, there are two types of correlations.
00:43
So we have positive correlations and then we have negative correlations.
00:54
So in a positive correlation, as our variable number one increases, our variable number two will also increase.
01:04
So for simplicity, i'll just call our two variables, variable a and variable b.
01:08
So when you have a positive correlation, both of those variables, increase as one another increases as well.
01:15
So i want to write that down here.
01:17
Variable a increases as variable b also increases.
01:27
And i'll just write that little arrow to symbolize an increase.
01:29
So what this would look like on a graph is exactly like this.
01:36
So if we had variable b and variable a here, that's exactly what it would look like.
01:47
Like it's increasing...
