Answer to Question 2

The student should indicate that survey research can be used to gather statistical data from representative groups and the data can then be used to generalize to the larger population. Surveys have specific data collection techniques to ensure reliability and validity (discussion here). Surveys can be administered by questionnaire or interview. Observational research can be used to gather intimate information about a specific group within their natural setting. Participant observation gathers data while interacting with that group. Nonparticipant observation gathers data without having to interact with the subjects (from a distance). This data cannot be generalized to other populations.
