Survey design can produce not only descriptive summary, but also generalized statements based on large databases (Cohen, Manion, & Morrison, 2000, p. 171). Survey design is good for providing information for curriculum development, including needs analysis and program evaluation, as well as researching certain topics (Brown, 1997). It is also good at collecting data on groups too large to observe directly (Babbie, 2004). Data collection instruments, especially data from questionnaires, can be used to gather data in a relatively short period of time. This data can be analyzed statistically and result in generalizable results. For this reason, a complex survey can be used as the basis for a thesis or dissertation. In fact, surveys and their resulting data and interpretations can serve as the basis for a book. For example, Jarvis (1991) interviewed and surveyed university academics for a book on achieving tenure. He was able to expand sections of his questionnaire to sections in a book.
