Question

what does it mean to say that two variables are positively associated? negatively associated? what does it mean to say that two variables are positively associated? a. there is a relationship between the variables that is not linear. b. there is a linear relationship between the variables. c. there is a linear relationship between the variables, and whenever the value of one variable increases, the value of the other variable decreases. d. there is a linear relationship between the variables, and whenever the value of one variable increases, the value of the other variable increases.

Explanation:

Positive association in variables means when one variable's value rises, the other variable's value also rises in a linear relationship. Options A, B, and C do not correctly define positive association. Option A mentions non - linear relationship which is not relevant for positive association in the context of linear relationships being discussed here. Option B just mentions a linear relationship without the key aspect of co - increasing values. Option C describes a negative association where one variable increasing causes the other to decrease.

Answer:

D. There is a linear relationship between the variables, and whenever the value of one variable increases, the value of the other variable increases
