Calculate Karl Pearson’s coefficient of correlation from the following data taking deviations from Arithmetic mean and interpret the result.
Karl Pearson's correlation coefficient (r) formula is given by -
r=∑(X−Xˉ)(Y−Yˉ)(∑(X−Xˉ)2) ∗ (∑(Y−Yˉ)2)r = \frac{\sum(X-\bar{X})(Y-\bar{Y})}{\sqrt{(\sum(X-\bar{X})^2)\ *\ ({\sum(Y-\bar{Y})^2)}}}r=(∑(X−Xˉ)2) ∗ (∑(Y−Yˉ)2)∑(X−Xˉ)(Y−Yˉ)
