      The correlation coefficient r is a measure of the linear relationship between two variables paired variables x and y.. For data, it is a statistic calculated using the formula. r = The correlation coefficient is such -1 ≤ r ≤ 1. If y is a linear function of x, then r =1 if the slope is positive and -1 if it is negative.

      If your correlation coefficient is a larger negative number than the critical region, your data indicate a significant negative correlation. The closer your r-value is to —1.0, the stronger the negative correlation. REPORTING YOUR RESULTS. The examples below show how the results of your analysis of linear correlation should be presented.
