mode of administration
The way the survey is administered, such as face to face, by phone or mail, or online
moderator
A professionally trained person who leads the discussion in a focus group
mutually exclusive
Preset response categories that do not overlap with one another, ensuring that respondents select the single category that best captures their views
natural experiment
An experiment in which the independent variable is manipulated by “nature,” not by the experimenter
observer
One of the four roles a researcher can adopt when doing fieldwork; the researcher tells people they are being observed but does not take part in the subjects’ activities and lives
