  While being an important and often used research method, survey research has
been less often discussed on a methodological level in empirical software
engineering than other types of research. This chapter compiles a set of
important and challenging issues in survey research based on experiences with
several large-scale international surveys. The chapter covers theory building,
sampling, invitation and follow-up, statistical as well as qualitative analysis
of survey data and the usage of psychometrics in software engineering surveys.
