Is there a significant relationship between The best way to avoid this is to send your survey to a few people in your target audience who you think would disagree with you on the topic. Bias in Self-Reported Behavior Generally speaking, people have less precise memories of the mundane behaviors they engage in on a regular basis, and they usually do not mentally categorize events by periods of time e.

Understanding Differing Customer Attitudes The most basic objective of customer satisfaction surveys is to generate valid and consistent customer feedback i. Mix up these close-ended question types to increase your response rate: Therefore, care should always be taken to sample from a random selection of landings at random times.

To estimate the magnitude of this bias, the researcher should have some idea about the population from which the sample is drawn. Corporate evaluations include not only their own customer satisfaction ratings but also those of their competitors.
