Using a scatter plot.
00:03
A scatter plot shows a correlation or lack thereof between two variables, x and y, by showing us a bunch of different data points, right? so here, this would be a scatter plot between x and y, where each of these points, let's say this one, contains two pieces of information.
00:22
They contain a value for x and a value of y.
00:25
And by scattering them, we are examining how they behave as x and y change.
00:33
So a, this is true, right? and the one i've drawn, you can see there is a positive relationship.
00:39
As the x value increases, the value of y tends to increase.
00:43
So yes, absolutely.
00:45
Scatter plots can show you if they're positively associated.
00:50
Similarly, c, absolutely, right? they can be.
00:54
They show a relation.
00:55
In fact, right? a implies c.
01:01
A positive association is a type of relation.
01:05
If things are positively associated, then they are also related...
