Find Sample Correlation Coefficient
Find Sample Correlation Coefficient. If you have the whole data (or almost the whole) there are also another way how to calculate correlation. If x, y are two random variables with zero mean, then the covariance covxy = ex · y is the dot product of x and y.
Next, each variable's standard deviation is .
The standard deviation of x is the length . If x, y are two random variables with zero mean, then the covariance covxy = ex · y is the dot product of x and y. In this case you must use biased std . Press the submit data button to perform the calculation.
