Question

Quizplus · Accepted Answer

Inspecting the sign of the correlation coefficient (r) will determine the direction of the relationship (positive or negative). A positive relationship indicates that as the number of publications of faculty members increase, the number of graduate programs offered also increase. A negative relationship indicates the opposite. Therefore, determining the sign of the correlation coefficient is crucial in determining the nature of the relationship. eta-squared (option B) and post-hoc tests (option C) are not appropriate for determining the nature of the relationship in a correlation analysis. Option D is an invalid formula. Option E is incorrect as eta-squared (option B) is not appropriate for this analysis.
