Two-way two-mode data occur in almost every domain of scientific psychology. The information present in sui,h data, however, may be hard to grasp because of the dimensions of one or both modes. Two-mode partitioning, addresses this problem by breaking down both modes into a number of mutually exclusive and exhaustive subsets. Although such a technique may be very useful, up to now, software-and consequently, two-mode partitioning-has been available only to a handful of specialists in the field. In this article, we present a free, easy-to-use MATLAB graphical user interface (TwoMP) for two-mode partitioning models, specifically developed for nonspecialist users. A short formal introduction is given on the statistics of the method, and the basic use of TWoMP is demonstrated with an example.
