Question

select all that apply. to describe the direction of an association, say there is
□ a strong association
□ a linear association
□ a positive association
□ a nonlinear association
□ a negative association
□ a weak association
□ no association

Explanation:

To determine the direction of an association between two variables, we consider if as one variable increases, the other tends to increase (positive association) or decrease (negative association). "Strong/weak" refer to the strength, "linear/nonlinear" to the form, and "no association" means no relationship. So only positive and negative describe direction.

Answer:

• a positive association
• a negative association
