3. • Experimental is most scientifically sophisticated
research method which is defined as
‘observation under controlled conditions’.
• Experimental research design are concerned
with examination of the effect of independent
variable on the dependent variable, where the
independent variable is manipulated through
treatment or intervention(s), & the effect of
those interventions is observed on the
dependant variable (Patidar, J., 2007).

Experimental designs are considered true
experiments when they employ randomization
in the selection of their samples and control for
extraneous influences of variation on the
dependent variable (Cook, T.D. & Campbell, D., 1990).

Pre-experimental designs should not be
considered true experiments, and are not
appropriate for formal research. Data collected
with these designs is highly suspect. We will
consider the One Shot Case Study design, the One
Group Pretest Posttest design, and the Static
Group comparison design (James, E., 2008).
