In statistics, a probability plot is a graphical technique for comparing two data sets, either two sets of empirical observations, one empirical set against a theoretical set, or (more rarely) two theoretical sets against each other. It commonly means either:

  • P-P plot, "Probability-Probability" or "Percent-Percent" plot;
  • Q-Q plot, "Quantile-Quantile" plot.
