Answer

The dependent variable increases as the independent variable increases.

Work Step by Step

Two variables are positively correlated when the value of the dependent variable increases when the value of the independent variable increases. For example, suppose we are trying to investigate whether there is a relationship between income (our independent variable) and expenditure (our dependent variable). If we find that expenditure INCREASES when income INCREASES then we can conclude that there is a positive correlation between income and expenditure.
