In simple linear regression analysis, the coefficient of correlation (or correlation coefficient) is a statistic which indicates the relationship between the independent variable and the dependent variable. The coefficient of correlation is represented by r and it has a range of -1.00 to +1.00.

**When the coefficient of correlation is a positive amoun**t, such as +0.80, it means an increase in the independent variable will result in an increase in the dependent variable. Also, a decrease in the independent variable will mean a decrease in the dependent variable.

**When the coefficient of correlation is negative**, such as -0.80, there is an inverse relationship. An increase in the independent variable will mean a decrease in the dependent variable. A decrease in the independent variable will mean an increase in the dependent variable.
