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 linear relationship between the variables b. there is a linear relationship between the variables, and whenever the value of one variable increases, the value of the other variable decreases. c. there is a linear relationship between the variables, and whenever the value of one variable increases, the value of the other variable increases. d. there is a relationship between the variables that is not linear.

Explanation:

Positive association means that as one variable increases, the other variable also increases. Option C correctly describes this relationship as having a linear relationship (implied in the context of association discussions in statistics) where an increase in one variable leads to an increase in the other. Option A is too general (just says linear relationship without the direction of association). Option B describes a negative association. Option D is about a non - linear relationship which is not what positive association (in the common statistical sense) is about.

Answer:

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