What Does Sample Correlation Coefficient Mean. The sample correlation coefficient, r, estimates the population correlation coefficient, ρ. The sample correlation coefficient (r) is a measure of the closeness of association of the points in a scatter plot to a linear regression .

The correlation coefficient, r, tells us about the strength and direction of the linear relationship between x1 and x2. It indicates how closely a scattergram of x,y points cluster about a . The correlation coefficient is a statistical measure that calculates the strength of the relationship between the relative movements of two variables.

The sample data are used to compute r, .

That means that it summarizes sample data without letting you infer anything about the population. There are several types of correlation coefficient, . The sample correlation coefficient (r) is a measure of the closeness of association of the points in a scatter plot to a linear regression . Correlation coefficients whose magnitude are between 0.9 and 1.0 indicate variables which can be considered very highly correlated.
