From any problem
statement, it is generally possible to derive more than one hypothesis. Formulating
hypothesis is important to narrow a question down to one that can reasonably be
studied in a research project. The formulation of the hypothesis basically
varies with the kind of research project conducted:
• Qualitative method.
• Quantitative method.
·
QUALITATIVE
METHOD
The enquirer uses research
questions, not objectives or hypothesis.
• The enquirer poses a central
question, which is being examined in the study in the most general form-“ the
broadest question that can be asked in a study.”
• Several sub-questions are raised related to
the central question to narrow the focus of study but to leave the questioning
at an open end.
• They are under continual review
and restructuring along the course of research.
• Questions begin with “what”,
“how”
• They focus on a single concept.
• The questions use
non-directional terminology.
- QUANTITATIVE METHOD
The researcher uses questions and
hypothesis to compose and focus the purpose of study.
• Hypothesis or research
questions:
·
May
be used to compare the variables.
·
May be used to relate the variables.
·
May
be used to describe the variables.
·
The
research follows from a test of theory and the question and the hypothesis or
the research questions are included in the theory
·
Independent
and dependant variables are measured separately.
·
Not
a combination of both. Either a research questions or a hypothesis.
o Some problems
- Lack of knowledge and clarity
of the theoretical frame work of the area in which the investigator
chooses to work.
- Lack of ability to make use of
the theoretical frame work logically.
- Lack of acquaintance with
available research techniques. This result in failure of phrasing the
hypothesis properly.
- Vagueness of the statement
