Explanation / Answer

Answer:

Locate the weakest correlation coefficient (i.e., closest to zero). Report the r value and identify the two variables. Give a verbal interpretation of the correlation coefficient using the variable descriptions.

Weakest correlation coefficient r = -0.128.

The variables are instructor’s perceived knowledge of subject and enrolment in course.

When the instructor’s perceived knowledge of subject increases, the enrolment in course decreases.
