What is research?
• “A careful, systematic , patient study and
  investigation in some field of knowledge,
  undertaken to establish facts or princilpes”
  (Grinnell, 1993:4)
• It is a discovery (Rediscovery); A voyage from
  the known to the unknown
• An effort to be closer to the truth
Characteristics
• It is controlled. In real life for an outcome
  there could be many affecting factors. In a
  study of cause and effect relationships one
  has to link effects with causes and causes with
  effects. Establishment of this linkage is
  impossible unless it is a laboratory test.
  Therefore instead of controlling external
  factors we have to quantify the impact of such
  factors.
Contd.,
• It is rigorous. Procedures followed to find
  answers to a problem must be relevant,
  appropriate and justifiable. Researcher needs to
  be very careful about this.
• It is systematic. Procedures adopted for a
  research should follow a logical sequence. Some
  procedures must follow others.
• It should be valid and verifiable. Your research
  conclusion based on findings should be correct
  and can be verified by you as well as others.
Contd.,
• It is empirical. The conclusions of the research
  should be based on evidence gathered from
  information collected from real life
  experiences/ observations
• It is critical. Research procedures and methods
  applied should withstand critical scrutiny.
  They must be foolproof and free from
  drawbacks
Research process- Steps
•   1. Formulation a of a research problem
•   2. Creation of a research design
•   3. Constructing instruments for data collection
•   4. Selecting a sample
•   5.Writing the research proposal
•   6. Collecting data
•   7. Processing data
•   8. Writing the report
Formulating research problem
•   Tasks:
•   Literature review
•   Formulating the research problem
•   Identifying variables
•   Constructing hypotheses
Literature review
• To make your research problem clear and
  bring focus into it
• Develop your methodology
• To know where you are
• To have a broader knowledge in your area of
  research
Contd.,
• Search and select literature pertaining to your
  area
• Review selected literature
• Develop a theoretical framework (theories
  and issues related your study)
• Develop a conceptual framework (aspects you
  select from theoretical framework that form
  the basis of your research)
Contd.,
•   Sources:
•   Books
•   Journals
•   Electronic resources: online and offline
How to write the literature review
•   Write under themes
•   Some may follow chronological order
•   Highlight your arguments
•   Provide references
Formulating research problem
• Any question that needs answer can be a
  research problem. However, not all questions
  can be transformed into research problems.
• What matters here:
• Your knowledge in research methodology
• Your knowledge of the subject area
• Your understanding of the issues to be
  examined
Contd.,
• Formation of a research problem is the first
  step in the research. Identify the destination
  before you start the journey. It is the
  foundation of your building.
• Sources of research problems:
• People (individuals, groups, organizations,
  communities)
• Problems (Issues, situations, associations,,
  needs, demographic)
Contd.,
• Programmes (contents, structure, outcomes,
  attributes, satisfaction, users, consumers)
• Phenomenon (cause and effect relationships,
  study of a phenomenon itself)
• Research problem is your topic.
• Consider the following when selecting a topic:
• Your interest
• Your level of expertise as well as of your
  supervisor
Contd.,
• Use concepts that can be measured
• Topic should be relevant to your profession/
  subject area
• Availability of data
• Ethical issues
Formulation of objectives
•   Objectives are goals of your study
•   Main objectives
•   Secondary or sub-objectives
•   They must be clear, complete and specific
Identifying variables
• A concept or perception that takes on
  different values and that can be measured is a
  variable. It is something that varies.
• Types:
• Independent variables (they are responsible
  for bringing about change in a phenomenon,
  situation)
Contd.,
• Dependent variables (effects of a change
  variable, the outcome of the changes brought
  about by changes in an independent variable)
• Extraneous variables (other factors that affect
  the changes bring about by independent
  variables)
• Intervening variables (those that link the
  independent and dependent variables)
Constructing hypotheses
• It is an ‘anticipation of nature’ or a hunch,
  assumption, assertion
• “a tentative statement about something, the
  validity of which is usually unknown’ (Bailey,
  1976:126)
• It may be right, partially right or wrong
• It should be simple, specific and conceptually
  clear
Research design
• It is the plan, structure and strategy of
  investigating the research problem
• It is an operational plan
• Procedures to be adopted
• Testing the design
Constructing an instrument for
            data collection
•   Data collection methods:
•   Primary sources
•   Observation
•   Interview
•   Questionnaire
•   Use of secondary sources
•   Establish the validity of the selected
    instrument
Selecting a sample
• “Process of selecting a few from a bigger
  group”
• Bigger group is the population and the
  selected few is the sample
• Larger the sample size the more accurate will
  be the findings
Sampling types
• Sampling strategies are numerous. They can
  be categorized into three groups:
• Random/probability sampling
• Non-random/probability sampling
• Mixed sampling
Research proposal
• It is your plan of research
• It reveals what you are going to do, how you
  plan to do and why you have selected the
  proposed procedures
• It guides you as well as your supervisor
• It is an academic piece of writing
• It shows the strength of your proposed
  research
Elements
• Introduction (an overview of the main area
  under study, historical background,
  philosophical issues etc., trends, major
  theories, main issues under consideration
  etc.)
• Importance (Why you do it? What are the
  benefits?)
• Problem (Your research problem or the
  research questions)
• Literature review
Contd.,
• Objectives ( main and secondary)
• Hypotheses
• Study design (population, sample, data
  collection methods etc.)
• Setting (brief description of the community,
  organization or agency in which you are going
  to carry out the research)
• Analysis of data (methods you are going to
  use)
Contd.,
•   Structure of the report or chapterization
•   Limitations and problems you may encounter
•   Work plan or schedule
•   Budget (optional)
Collection data
• Ethical issues relating to research participants
  ( their consent, incentives, sensitive
  information, harm to participants etc.)
• Ethical issues relating to the researcher
  (avoiding bias, using appropriate research
  methodology, correct reporting etc.)
Processing data
•   Editing data
•   Coding data
•   Verifying coded data
•   Analyzing data
•   Displaying data (charts, diagrams, tables)
Writing the report or thesis
• Follow standards (International standards or
  departmental guidelines)
• Use appropriate referencing/citation system
• Preparation of a bibliography
• Avoid plagiarism
