WebMay 16, 2024 · The Pearson sample correlation coefficient can be written as: r = 1 n − 1 ∑ i = 1 n z 1, i ⋅ z 2, i z k, i = x k, i − x ¯ k s k. This result means that the sample correlation of two vectors x 1 and x 2 is equivalent to the sample correlation of their z-scores z 1 and z 2 (i.e., sample correlation is determined through the z-scores). WebPearson Correlation Formula The correlation coefficient is the measurement of the correlation between two variables. Pearson correlation formula is used to see how the …
