Formulation of Hypothesis : Some problems

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
