Interpret coefficient of correlation
WebThe information given by a correlation coefficient is not enough to define the dependence structure between random variables. The correlation coefficient completely defines the dependence structure only in very particular cases, for example when the distribution is a multivariate normal distribution. (See diagram above.) WebThe correlation coefficient r is a unit-free value between -1 and 1. Statistical significance is indicated with a p-value. Therefore, correlations are typically written with two key numbers: r = and p = . The closer r is to zero, the weaker the linear relationship. Positive r values indicate a positive correlation, where the values of both ...
