Like height and IQ, or height and weight, different degrees of relationship  could occur. For example suppose we go around a typical class and ask  each person for their height and IQ and we plot the left scatter plot below.  We go up the Y-axis their height then across the X axis their IQ. We place  a dot in that spot to represent that a person with that height and that IQ  occurred. We notice that there are more people of average height than very  tall or very short. This could be seen by imagining that each dot is a ball  bearing and we tilt the page to the left. If the bearings roll straight to the  left they would form stacks against the Y-axis as is illustrated. There  would be many in the middle, few to the top or bottom. We can of course do  the same with IQ along the X-axis. Many would be in the middle and few  to the left or right. Next we repeat the whole plotting process by asking
