What is research problem?
• Any question that you want answered and any
assumption or assertion that you want to challenge or
investigate.
• However;
– not all questions can be transformed into research
problems.
– the process of formulating them in a meaningful way
is not at all an easy task.
– it requires considerable knowledge of both the subject
area and research methodology.

What is research problem? (cont.)
• A research problem is a perceived gap between what is
and what should be.
• Research problem arise from;
– Evolution of theories.
– Peers and supervisors etc.
– Published research (literature review).
– Day-to-day experience

The way we formulate the research
problem determines every step that
follows;
• type of study design that can be used
• type of sampling strategy that can be employed
• research instrument that can be used or developed
• type of analysis that can be undertaken

Identifying research problem
• Differentiate between research vs. non-research
problems.
• Non-research problems are answered by these
questions:
– Can it be solved by administrative changes?
– Are there already solutions available that can be used?
– Is the problem due to lack of manpower and resources?
– Is there data showing that it is not a significant issue?

• Relevance
• How important?
• Size, severity, health & social consequences?
• Duplication
• Is the answer already available from other studies?
• Feasibility
• Feasible to carry out remedial actions?
• Are the manpower, time and resources available?
• Applicability
• Potential solution is effective under ideal conditions?
• Will managers accept and use it?

• Cost effectiveness
• Are the resources invested worth the outcome?
• Will the solution be too expensive to implement?
• Timeliness
• Will the answer come quick enough?
• Ethics
• Will the project be acceptable to the respondents?
• Political acceptability
• Will the managers and community accept the
results?

Formulation of research objectives
• What is an ‘objective’?
– A clear and specific goals you set out to attain in your
study.
• Two types of objectives;
– Main objectives
• Specific objectives / sub-objectives
20
MAIN OBJECTIVES
• Overall statement of the thrust of
your study.
• It is also a statement of the main
associations and relationships
that you seek to discover or
establish
SUB-OBJECTIVES
• The specific aspects of the topic
that you want to investigate
within the main framework of
your study
• One sub-objective contains one
aspect only
S C H O O L O F N U T R I T I O N A N D D I E T E T I C S • U N I V E R S I T I S U L T A N Z A I N A L A B I D I N
Formulation of research objectives (cont.)
• Sub-objectives should be numerically listed.
• Worded clearly and unambiguously.
• Use action-oriented words or verbs when writing your
objectives.
• E.g. start with;
– ‘to determine’, ‘to find out’, ‘to ascertain’, ‘to measure’
and ‘to explore’
• the wording of your objectives determines the type of
research design you need to adopt to achieve them.
21
S C H O O L O F N U T R I T I O N A N D D I E T E T I C S • U N I V E R S I T I S U L T A N Z A I N A L A B I D I N
Functions of research objectives
• Focus the study (narrowing it down to essentials).
• Avoid the collection of data which are not strictly
necessary for understanding and solving the problem
you have identified.
• Organize the study in clearly defined parts or phases.

Establishing operational definition
• Working definitions or operational definitions are
pre-defined concepts that you plan to use either in your
research problem and/or in identifying the study
population in a measurable form.
• Used only for the purpose of your study and could be
quite different to legal definitions, or those used by
others.
• Working definitions will inform your readers what exactly
you mean by the concepts that you have used in your
study to avoid ambiguity and confusion.
