Question

what type of relationship occurs when two variables both increase or decrease together?
an inverse relationship
a positive relationship
a direct relationship
an indirect relationship

Explanation:

In statistics (a sub - field of Mathematics), when two variables move in the same direction (both increase or both decrease), it is called a positive relationship. An inverse relationship means one variable increases while the other decreases. A direct relationship is more about a proportional change (like \(y = kx\) in a simple linear case, which is a type of positive relationship but the term "positive relationship" is more general in the context of variable co - movement). An indirect relationship is not a standard term for this co - movement of variables.

Answer:

B. a positive relationship
