Moreover
under the experimental method Scott & Usher (2011) described some types of
the study design such as One-Off Case study design,  Single-group experimental design, the static
group comparison, the pre-test and post-test control group design and factorial
design (pg 63-65). Other research methods which research may adopt are survey
and correlation designs which  are underpinned by the positivist epistemology
and direct realist ontology. Survey researchers collect data in relation to generously
proportioned populations as compared to experimental one which involve smaller
quantity of data. Survey has one common known benefit in the sense that data
are collected from larger number of respondents hence it covers larger
geographical area. In doing this the questions are normally in the form or
structured interview, semi structured interview or questionnaire.  Another research method is the qualitative
research design, case study and theory construction. The qualitative approach involves
the process of coding or classification of the field notes obtained from observation
or interview transcripts by inferring either from the words being examined what
is significant basing on the respective theory or on the way in which the case
is being understood.  The second step in
qualitative method is to examine the categories for the purpose of identifying
the inter-relationships among the expression or words. This course of action
helps the investigator to extend the relationship of the general context which
later helps to make connotation and have trustworthiness outside the precincts
of the case so being investigated. Another step is to make explicit patterns,
commonalities and differences and then to take these by now more developed hypothetical
constructs into the field to investigate or filter them which later will help
to unequivocal and make oversimplification that certain relationships hold firm
in the setting being examined. Generally according to Miles and Huberman (1994)
three processes are being involved in the qualitative reseafrch namely: data
reduction, data display and conclusion drawing and verification
