Question

Professor Karney administered a psychological test measuring shyness to a large number of undergraduate students. The students also completed a lengthy questionnaire on their social life and activities, including number of friends. Professor Karney conducted a statistical analysis of the responses and found a correlation coefficient of –.80 between level of shyness and number of friends. This indicates that:___________.

Answer 1

as number of friends decreases, level of shyness increases

Step-by-step explanation:

The correlation coefficient can take values which ranges from +1 to -1.

0 is a value which shows that any two variables are not associated with each other. A value that is more than 0 shows the positive association, that is, one variable's value increases as the other variable's value do so.

Here in the question the correlation coefficient of –.8 shows that the level of shyness increases as the number of friends increases.

Thus the answer is --

as number of friends decreases, level of shyness increases.
