Patent US 7,408,554

In one aspect, the invention relates to a method for analyzing qualitative data. The method includes the step of providing a plurality of evaluation categories and a respective ranking system. Providing a closed curvilinear graph in which each unit of radius corresponds to a rank in the ranking system is another step of the method. Another step in the method includes placing each evaluation category at a location on the circumference of the closed curvilinear graph. The steps of the method also include providing the evaluation categories and ranking system to an entity being evaluated. The entity selects a rank in response in each respective category according to the method. Plotting the ranking of each respective category as a node in the closed curvilinear graph in response to the ranking by the entity is another step in the method.
