ABSTRACT
Chapters 6 through 8 provided human factors research methods that can be used to perform thorough observation. As broad as they are, observation methods may not fit some occasions when it is necessary to obtain information from people. For example, it may be necessary to learn about the ways that members of a group understand or value a routine way of doing something, or how individuals perceive a product or institution. In such cases, it can be useful to employ survey methods such as conducting interviews or administering questionnaires.
