Abstract: Surveys and questionnaires are among the analyst's most important sources of information about user problems, user requirements, user satisfaction, and similar system parameters. This chapter discusses sample surveys and questionnaire design. A sample survey is taken when it is not practical or convenient to conduct a census of an entire population. Survey results based on a proper sampling plan can be more accurate than the results of a census of an entire population. This can happen because a survey can often be conducted by a small number of highly trained field workers who are far less apt to make mistakes than are the possibly large number of field workers who would be needed to conduct a census. Errors of observation occur when the survey data that has been collected is different from the truth. One of the best ways to reduce error when conducting a sample survey is to carefully design the questionnaire to be used.
