Drew is interested in assessing the degree of relationship between belonging to a Greek organization and the number of alcoholic drinks consumed per week. Drew should use the point-biserial correlation coefficient to assess this.  

This term is used in statistics. When the researcher wants to measure the association of a continuous variable and another dichotomous variable.

Explanation:

Many years ago, early humans lived in the jungle and were afraid of bigger and stronger animals. They did not know how to build houses. So, they spent their time on the trees or hid themselves behind the bushes. But all this could not help them to save themselves from wild animals and harsh climatic conditions.

In the Paleolithic period (roughly 2.5 million years ago to 10,000 B.C.), early humans lived in caves or simple huts or tepees and were hunters and gatherers. ... They used combinations of minerals, ochres, burnt bone meal and charcoal mixed into water, blood, animal fats and tree saps to etch humans, animals and signs.
