A study that has a set of questions asked of a number of respondents and a set of corresponding answers. An evaluation tool evaluates every answer to a selected question to identify key terms therein, and develops a corresponding key term cloud based on the identified key terms of the selected question. The cloud is a visual representation of the identified key terms such that each key term appears in the cloud in a relative manner based on an attribute of the key term with regard to the answers. The tool displays the developed cloud for the selected question with the answers for the selected question, and a study evaluator views the relatively appearing key terms in the displayed cloud. Based thereon, the evaluator discerns trends in the answers to the selected question.
