How do you calculate Karl Pearson's correlation coefficient?
Can you explain to me how to calculate Karl Pearson's correlation coefficient?
Certainly! Karl Pearson's correlation coefficient is a measure of the strength and direction of the linear relationship between two variables. The formula for calculating it is as follows: r = sum((x - mean(x))*(y - mean(y))) / sqrt(sum((x - mean(x))^2) * sum((y - mean(y))^2))
