Pearson Correlation Coefficient Formula

Correlation(r) = NΣXY - (ΣX)(ΣY) / Sqrt([NΣX2 - (ΣX)2][NΣY2 - (ΣY)2])


N = Number of Values or Elements

X = First Score

Y = Second Score

ΣXY = Sum of the Product of First and Second Scores

ΣX = Sum of First Scores

ΣY = Sum of Second Scores

ΣX2 = Sum of Square of First Scores

ΣY2 = Sum of Square of Second Scores
