Quizplus · Accepted Answer

The sign of the correlation coefficient (either positive or negative) indicates the direction of the relationship between two variables. A positive correlation coefficient indicates a positive relationship (as one variable increases, the other variable also tends to increase), while a negative correlation coefficient indicates a negative relationship (as one variable increases, the other variable tends to decrease). The number itself indicates the strength (magnitude) of the relationship. The mode and median are measures of central tendency and are not relevant to determining the relationship between two variables.
