The order in which survey questions are presented may bias how subsequent questions are interpreted. Also, the wording of a survey question strongly influences the answer. Structuring your survey questions as statements has proven to be the most effective means of evaluating the psychological constructs of attitudes, opinions, and beliefs, across a wide range of variables. It is recommended that survey questions be written by psychologists, trained in creating psychological tests (surveys) without the biasing effects of wording inherent in surveys written by lay persons. Questions should be valid, reliable tools to be used with confidence to fully evaluate the topics selected. And, questions should be tested and standardized. Utilizing standardized questions allows you to compare your scores against other companies who have used identical questions. This comparison is known as benchmarking.
