RE: Card sorting!!!

Hi

Generally, card sorting is carried out on individuals while affinity diagramming is a group activity. This means that AD results are subject to group dynamics to reach consensus while this is not so for CS as the responses are individual and it is the analysis which provides the 'consensus' which is reflective of the group.
