First, does it look like the values of y are increasing as the values of x increase? The answer is yes, so the correlation must be positive. If they were decreasing, the correlation would be negative.

In statistics, the coefficient of multiple correlation is a measure of how well a given variable can be predicted using a linear function of a set of other variables. It is the correlation between the variable's values and the best predictions that can be computed linearly from the predictive variables. Multiple Regression Assessing "Significance" in Multiple Regression(MR) The mechanics of testing the "significance" of a multiple regression model is basically the same as testing the significance of a simple regression model, we will consider an F-test, a t-test (multiple t's) and R-sqrd.

Interpreting the Correlation Coefficient. A correlation of, say, r = 0.80 does not mean that 80% of the points are tightly clustered around a line, nor does it indicate twice as much linearity as r = 0.40. The correlation measures the extent to which knowing the value of X helps you to predict the value of Y. The correlation coefficient is a measure of how well a line can describe the relationship between X and Y. R is always going to be greater than or equal to negative one and less than or equal to one. If R is positive one, it means that an upwards sloping line can completely describe the relationship.
