WebA Quantile-Quantile (Q-Q) plot3 is a scatter plot comparing the fitted and empirical distributions in terms of the dimensional values of the variable (i.e., empirical quantiles). It is a graphical technique for determining if a data set come from a known population. In this plot on the y-axis we have empirical quantiles4 e on the x- The main application of a normal probability plot is to show whether or not data is approximately normally distributed. That is, it shows how random the data in a data set is.
