4. According to Kerlinger (1986) research design is
the plan, structure, and strategy of investigation
conceived so as to obtain answers to research
questions and to control variance.
The research design is the master plan specifying
the methods and procedures for collecting &
analyzing the needed information in a research
study

5. Variance
Variance is the measure of the dispersion or spread of a
set of scores. It describes the extent to which the scores
differ from each other.
