Overall, these limitations are a small price to pay for the benefit of quickly being able to iterate and evaluate major structural changes to an information hierarchy early in the design process. 0% average accuracy. Even if you are interested in testing only a specific section of the tree, excluding the other sections is risky because it assumes that users will know which section to go to. For example, a design with mega menus provides a quite different browsing experience than the one tested in a tree test, since it simultaneously displays the contents of several subcategories. Such a test is especially easy to do with Userzoom’s tree-testing tool, which allows you to randomly assign participants to different versions of the tree, in a manner similar to an A/B test on a live website. Once you have pasted your hierarchy into the testing tool, the categories are parsed and used to automatically create a clickable menu hierarchy in which each category can be expanded to show the corresponding subcategories. To simplify the computation, you can assume that the total cost of the tree is obtained by adding up the costs of encoding each internal node and each leaf node. You can also partially compensate for the inability to ask follow-up questions by including a short survey after the tree test. 6 hours ago.
