Abstract:

Card sorting is a user testing method for organising data into structure. There’s a lot of information about on what they are, how to conduct them. Problem is, they’re all over the place and mostly they’re written by scientists so tend to be a little difficult to grasp and bogged down in analysis (which can take over your life if you let it!) I’ve decided to document my understanding of how to plan, conduct and analyse a card sort, from a practitioners point of view.
