Tree testing is a usability technique for evaluating the findability of topics in a website. It is also known as reverse card sorting or card-based classification.〔(【引用サイトリンク】url=http://boxesandarrows.com/card-based-classification-evaluation/ )〕 A large website is typically organized into a hierarchy (a "tree") of topics and subtopics. Tree testing provides a way to measure how well users can find items in this hierarchy. Unlike traditional usability testing, tree testing is not done on the website itself; instead, a simplified text version of the site structure is used. This ensures that the structure is evaluated in isolation, nullifying the effects of navigational aids, visual design, and other factors. == Basic method == In a typical tree test: # The participant is given a "find it" task (e.g., "Look for brown belts under $25"). # They are shown a text list of the top-level topics of the website. # They choose a heading, and are then shown a list of subtopics. # They continue choosing (moving down through the tree) — drilling down, backtracking if necessary – until they find a topic that satisfies the task (or until they give up). # The participant does several tasks in this manner, starting each task back at the top of the tree. # Once several participants have completed the test, the results are analyzed for each task. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Tree testing」の詳細全文を読む スポンサード リンク
