Multiple quantile plots provide a powerful graphical method for comparing the distributions of two or more populations. This paper develops a method of visualizing triple quantile plots and their associated confidence tubes, thus extending the notion of a QQ plot to three dimensions. More specifically, we consider three independent one-dimensional random samples with corresponding quantile functions Q 1, Q 2 and Q 3, respectively. The triple quantile (QQQ) plot is then defined as the three-dimensional curve Q(p)=(Q 1(p), Q 2(p), Q 3(p)), where 0
