Question: Identify the methods by which marketing researchers collect primary data. Observation data are gathered by observing consumers via devices such as people meters or videotape. Survey data can be collected through telephone interviews, mail or fax surveys, personal interviews, focus groups, or a variety of online methods. Telephone interviews provide more than half of all primary marketing research data. They give the researcher a fast and inexpensive way to get small amounts of information but generally not detailed or personal information. Personal interviews are costly but allow researchers to get detailed information from respondents.

Mail surveys are a means of conducting national studies at a reasonable cost; their main disadvantage is potentially inadequate response rates. Focus groups elicit detailed, qualitative information that provides insight not only into behavior but also into consumer attitudes and perceptions. Online surveys can yield fast responses but face obstacles such as the adequacy of the probability sample. The experimental method creates verifiable statistical data through the use of test and control groups to reveal actual benefits from perceived benefits.
