Σy 2 the sum of squared y scores. Here cov is the covariance. Using Correlation Coefficient.
Correlation r NΣXY - ΣX ΣY Sqrt NΣX2 - ΣX2 NΣY2 - ΣY2 Formula definitions.
Xm Mean of Data set X. N number of values or elements in the. In the case 2 the corresponding p-value is determined using t distribution table for d f n 2. Xm Mean of Data set X.
