Understand what a positive association means in statistics: it describes a relationship between two variables where they tend to move in the same direction.
Recall that if two variables have a positive association, when one variable increases, the other variable also tends to increase.
Contrast this with a negative association, where one variable increases while the other tends to decrease.
Recognize that 'no consistent relationship' means the variables do not show any predictable pattern of movement together, and 'both variables remain constant' means no change occurs in either variable.
Therefore, the best description of a positive association is: 'As one variable increases, the other variable also tends to increase.'
