Drawing from information that emerges from this analysis, establish a thesis regarding the function of the behavior. Do not start in the middle of your argument. Construct a step by step proof. You must show that the two show correlation, that the two tend to occur in unison. That is, as one changes, the other also changes.
Correlation can be either positive or negative.
Remember that two factors often appear correlated only because each is being caused by some third, unnoticed factor. A necessary cause must be present for an effect to occur, but by itself cannot cause the occurrence of the effect. A contributory cause is one that may produce an effect but cannot produce the effect by itself. A sufficient cause is one that can produce an effect by itself. Therefore, I did not do my best on the test.
