Survey paradata are data that are captured about the context and processes surrounding survey data collection. Many types of paradata are automatically produced and collected, primarily by the software systems used for computerized interviewing, but little is known about best practices for how the range of these available paradata should be used. This chapter identifies some of the most commonly used forms of paradata, such as response times and call record data, and discusses how they have been studied and used in practice. By understanding how these types of paradata are used effectively, researchers may be able to identify new uses for other forms of paradata. The chapter also proposes a number of areas for future research that will maximize the value of paradata for researchers moving forward.
