Correlation coefficient
The correlation between x and y will be significant at the given probability level if your calculated value of r exceeds the tabulated r value. Note 1: you should ignore the sign (+ or ) of your r value when reading this table. Note 2: the value of r ALWAYS lies between 0 and 1 (or 0 and 1). If your calculated r value is more than 1 (or less than 1) then you made an error in your calculations. Note 3: If you cannot find the required degrees of freedom, use the next lowest one.
