Question

Quizplus · Accepted Answer

The value of the Pearson correlation coefficient (r) indicates the strength of the relationship between two variables. A value close to +1 or -1 indicates a strong positive or negative relationship respectively, while a value close to 0 indicates little to no relationship. The direction of the relationship is indicated by the sign (+/-) of the coefficient. However, the question specifically asks for the assessment of the strength of the relationship, therefore the answer is C. Statistical significance is also important, but not specified in the question as the primary focus.
