Figure 5-4: “
Strong” positive linear association
Figure 5-5
shows variables that are negatively related. The values are not
on a straight line, but are somewhat closely packed together in a linear
manner, and so one could possibly say that there is a “strong” negative linear
association between the two variables. We will define what we mean by
“strong” in a later discussion.
