Non-experimental research is research that
lacks the manipulation of an independent variable, control of extraneous
variables through random assignment, or both. There are three broad types
of non-experimental research. Single-variable research focuses
on a single variable rather than a relationship between variables.
Types
of Non-Experimental Research
I. Pure descriptive design
Obtain information about a current existing phenomenon of
interest in terms of frequency of occurrence rather than to describe a
relationship between variables.
II. Correlational descriptive research
design Explores the interrelationship between variables of
interest without any active intervention or manipulation of the independent
variable by the researcher.
III. Other non-experimental research designs:
a) Surveys:
“Studies in which information is obtained from a population
or sample of individuals by means of self-report ”.
Self reporting means that the subjects responses to a series
of questions posed by the researcher.
b) Needs assessment:
A study in which a researcher collects data for estimating
the needs of a group, organization, or community.
c) Historical research:
It answers questions
or hypothesis regarding trends, causes, or effects related to past events that
may shed light on present behaviors, practices or phenomenon.
Data for such researches are found in written materials
whether books, periodicals, journals, reports, newspapers, letters, meetings
minutes, photos, films, tapes…etc..
d) Case studies:
An in-depth
investigation of an individual, family, group, or any small social unit. It
investigates a current phenomenon within its real life context, especially when
the boundaries between the phenomena and its context are not clear.
Case studies address multiple variables that are measured at
several points in time.
