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
ΣX^{2} = Sum of Square of First Scores
ΣY^{2} = Sum of Square of Second Scores

Correlation coefficient is a measure of degree between two or more variables. This measurement of correlation is divided into positive correlation and negative correlation. Positive Correlation happens when one variable increases, then the other variable also increases. Negative correlation happens when one variable decreases, the other variable also decreases. The correlation co-efficient differ from -1 to +1. Also, this **correlation coefficient calculator** page shows you the exclusive formula for the calculation of coefficient of correlation.
