What does it mean when we say two things are correlated, and what are positive and negative correlations. (Ap Psychology)

When two things are correlated, it means that the two variables have a relationship in which the variables affect one another.

When we talk about positive correlations, it means that the variables vary in the same direction (it shows an upward trend when graphed). For example, increased exercise and muscle gain are positively correlated. If you INCREASE exercise, muscle gains will INCREASE.

On the other hand, increased exercise and fat gain are negatively correlated. If you INCREASE exercise, fat gain is DECREASED. Negative correlations will have a downward trend when graphed.

Hope this helps!

If two things are negatively correlated, as one increases, the other decreases. As one decreases, the other increasese

b. as prices rise, quantity demanded goes down.
