Positive Correlation
A Positive Correlation is a steady relationship between two variables in the same direction, meaning that as the value of one variable increases, the value of the other increases as well. (And as the value of one variable decreases, so does the other).
For example, a child’s income level and his or her performance in school are positively correlated; children from wealthier or more financially stable homes tend to do better in school.
