Pearson correlation coefficient - Wikipedia
WebbWhen referring to the sample correlation coefficient, a lowercase r is used (often called “Pearson’s r”). Here is the equation for the population correlation: (4) ρ ( x, y) = 1 N ∑ i = 1 N ( x i − μ x) ( y i − μ y) σ x σ y This equation is used for the sample correlation : (5) r ( x, y) = 1 n − 1 ∑ i = 1 n ( x i − x ¯) ( y i − y ¯) s x s y WebbThe correlation coefficient, or Pearson product-moment correlation coefficient (PMCC) is a numerical value between -1 and 1 that expresses the strength of the linear relationship … potentiometer chemistry
