First, you need to create a scatter plot of tax base versus comfort.
00:26
So on the vertical axis, we're going to have assessed value of all city property.
00:51
This would be in billions of dollars.
01:08
And then we would put percent of assessed property value that is commercial property.
01:32
And that would be on the horizontal axis.
01:38
So we're going to create the scatter plot.
01:40
After we create the scatterplot, we need to analyze the relationship.
01:46
So our scatterplot will consist of dots.
01:50
And you can see that with this scatterplot, there's going to be a positive correlation.
01:59
Because the individual dots form the shape roughly of a straight line that's sloping upwards.
02:16
So that means that as one of these variables increases, the other also increases.
02:23
So then let's say that we get a scatterplot that looks more like this...
