This document discusses experimental research, which involves observing variables under controlled conditions. It defines experimental research as manipulating an independent variable through treatment or interventions to observe its effects on a dependent variable. It explains that the independent variable is the treatment that is measured and manipulated, while the dependent variable is the observed response. It also notes that control variables must be neutralized so they do not moderate the effects. Finally, it outlines the key steps in experimental research design as identifying the research question, reviewing literature, formulating hypotheses, determining the approach, and identifying the population and sample.

2.  Experimental research is most scientifically
sophisticated method.
 It 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 interventions is observed on the
dependent variable.

4.  Independent variable: treatment or intervention
variable, measured and manipulated
 Dependent variable: response variables,
observed aspect of the behavior of an organism
that has been stimulated.
 Variables of interest: correlation
 Control variable: A variables in a situation that
cannot be studies at the same time; must be
neutralized(e.g. gender, class level); neutralize
to ensure that it does not have a moderating
effect.

6.  Identifying the research question or problem
area
 Initial review of literature
 Distilling the question to a specific research
problem
 Continued review of literature
 Formulation of hypotheses
 Determining the basic research approach
 Identifying the population and sample
