Within these following graphs, what we'd like to know is if there's any sort of linear relationship that might exist between the explanatory and response variables.
00:09
And this is just based on what it looks like graphically.
00:11
So looking at these scatter diagrams, is there a linear relationship? and if there is, is it positive or negative? so let's start with nine right here.
00:19
And what i think is easiest to do when it comes to this is to actually try to draw whatever line or curve would best fit the data points.
00:27
So if we do that for nine right here, it looks like.
00:30
It would look something like this, which to me looks more exponential.
00:34
It's clearly not linear.
00:35
So for this one, we can't say that there is any linear relationship.
00:41
Now for 10, let's do the same thing and try to draw a line through it.
00:44
It looks like we could draw one fairly well...
