Professor Williams is researching loneliness. In analyzing the results of her study, Professor Williams finds that as the number of friends increase, the level of loneliness tends to decrease. This represents a negative correlation
Step-by-step explanation:
Correlation is a process with which the relationship between two or more things. It can be either positive or negative correlation. With the increase in one thing, if the other also increases, then it is a positive correlation.
But if with the increase in the one thing, the other decreases, then it is a negative correlation between both the things. In the research about loneliness, with the increase in the number of friends, loneliness tends to decrease, therefore it is a negative correlation.
