WebbThe solution is to (1) take the standard deviations of each variable, (2) multiply them together, and (3) divide the covariance by this product – the resulting value is called the Pearson correlation coefficient. When referring to the population correlation coefficient, the symbol ρ (pronounced “rho”) is used. Webb2 Abstract: The selection of an appropriate plotting plot formula for each statistical distribution is the most important step that is generally chosen by using the goodness of fit tests. Probability Plot Correlation Coefficient (PPCC) test which was developed by Filliben for normality is a powerful tool among the goodness of fit tests. PPCC test is based on …
