When using correlation coefficients to evaluate reliability, which of the following is undesirable?
A)A correlation coefficient close to 1
B)A negative correlation coefficient
C)A strong correlation coefficient
D)It depends on the type of reliability being evaluated.

Question

Quizplus · Accepted Answer

A negative correlation coefficient indicates that the two measurements are not related in a consistent manner and therefore do not have a high level of reliability. A correlation coefficient close to 1 or a strong correlation coefficient indicates a high level of consistency between the two measurements, which is desirable in measuring reliability. The choice may depend on the type of reliability being evaluated, but in general, a negative correlation coefficient is the most undesirable when evaluating reliability.
