Source sentences:
text: Suppose we have completed studies at three different banks, and we want to test whether the correlation between the test and customer service ratings is the same or different across banks.
text: The correlation coefficient will be the same if you use COVARIANCE.P and STDEV.P.
text: However, note that the covariance and correlation are exactly the same if the features are normalized to unit variance (e.g., via standardization or z-score normalization).
text: and concludes the proof that covariance and correlation are the same if the features are standardized.
