The third type is called panel surveys, which are
alternative versions of longitudinal surveys. It usually
lasts shorter period of time and asks questions of panel
members on a frequent basis. A panel member may be
asked question every month for a couple of years, while
in longitudinal survey, people are asked often once a
year (Moore, 2001).

psychology, political science, and economics, which
often work mainly in large, complex and populous
societies, unlike anthropologists, which have traditionally
worked among small-scale societies.
Experimentation: This quantitative method is
sometimes used in sociology. Sociologists conduct
experimental studies, following the procedures and
principles of experimentation. This is done usually to
explore cause and effect relationship between one and
the other social phenomena. What causes what? What
is the effect of one social phenomenon on the other?
