Proof that the Sample Bivariate Correlation Coefficient Has Limits ((Plus or Minus)) 1.
O'Brien, Francis J., Jr.
This paper presents in detail a proof of the limits of the sample bivariate correlation coefficient which requires only knowledge of algebra. Notation and basic formulas of standard (z) scores, bivariate correlation formulas in unstandardized and standardized form, and algebraic inequalities are reviewed first, since they are necessary for understanding the proof. Then the proof is presented, with an appendix containing additional proofs of related material. (MNS)
