Find The Value Of The Linear Correlation Coefficient R

Find The Value Of The Linear Correlation Coefficient R

Submitted by • July 24, 2012 www.tutorcircle.com

For finding the value of the Linear Correlation coefficient r, we use following Linear Correlation Coefficient formula-
Correlation coefficient r = N ∑xy - (∑x)(∑y) / √([N ∑x2 - (∑x)2]) . ([N ∑y2 - (∑y)2]),
Where N = data points in a set,
∑xy = summation of all values of xy,
∑x = summation of all values of ‘x’,
∑y = summation of all values of ‘y’,
∑x2 = summation of all values of x2,
∑y2 = summation of all values of y2,
