WebJun 16, 2010 · Correlation Coefficient. The correlation coefficient gives a mathematical value for measuring the strength of the linear relationship between two variables. r lies between -1 and +1. +1 indicates perfect positive relation. -1 indicates perfect negative relation. 0 shows no correlation. WebIf r is not between the positive and negative critical values, then the correlation coefficient is significant. If r is significant, then you may use the line for prediction. If r is not significant (between the critical values), you should not use the line to make predictions. Example 12.7 Suppose you computed r = .801 using n = 10 data points.
