Pearson correlation coefficient between
WebPearson’s correlation coefficient is the test statistics that measures the statistical relationship, or association, between two continuous variables. It is known as the best method of measuring the association between variables of interest because it is based on the method of covariance. WebA Pearson correlation is a number between -1 and +1 that indicates to which extent 2 variables are linearly related. The Pearson correlation is also known as the “product moment correlation coefficient” (PMCC) or simply “correlation”. Pearson correlations are only suitable for quantitative variables (including dichotomous variables ).

WebFor two variables X and Y, the Pearson correlation coefficient (rXY ), named after the English mathematician and biostatistician Karl Pearson, is a statistical measure of the degree of linear correlation between these two variables and is defined as follows [287]: (5.27) where. cov (X, Y) covariance between X and Y (see Eq. 5.5 ), σ Χ, σ Y. WebThe Person correlation coefficient, also known as the Person product-moment correlation or Pearson’s r, is a numerical measure of the strength of that relationship and varies from -1 (a perfect negative relationship) to +1 (a perfect positive relationship). A r value of 0 would mean that there is no relationship between the variables.
