Professor Williams is investigating loneliness. Participants in the study complete the UCLA Loneliness Scale to measure their level of loneliness. They also answer questions on a survey about many aspects of their personal life. In analyzing the results of her study, Professor Williams finds that as the number of friends increases, the level of loneliness tends to decrease. This represents a ________ correlation.A) postive
B) negative
C) spurious
D) couse-and-effect

Explanation: correlation refers to the fact that there exist a relationship between two variables in such that when one variable increases the other one increases (positive correlation ) or when the other one decreases the other one decreases just at the same point of time however this doesn't explain causation. It doesn't tell us what causes this type of relationship.

In this case the relationship is inversely correlated because when friendship goes up ,lonileness decreases .
