Question

Quizplus · Accepted Answer

Correlation coefficients can range from -1.00 to +1.00, indicating the strength and direction of the relationship between two variables. The closer the correlation coefficient is to -1.00 or +1.00, the stronger the relationship, while a coefficient close to 0 indicates a weak relationship. Correlation coefficients can be positive or negative, depending on the direction of the relationship, and can be calculated for variables measured at the interval or ratio level. Therefore, option A and B are incorrect, and option D is partially correct.
