                    Notes          4.  Data gathering method decision: Which communication mode is most appropriate - face-
                                       to-face interview or mailing? The choice of question structure depends largely on  the
                                       communication mode chosen.
                                   5.  Instrument drafting:  After determining the data required for the  study,  first, a broad
                                       outline of the instrument may  be drafted, listing the  various broad categories of  data.
                                       Second, the sequence of these groupings must be decided. Third, the questions to be asked
                                       under each group heading must be listed. All conceivable items relevant to the ‘data need’
                                       should be compiled.
                                   6.  Evaluation of the draft  instrument:  In consultation  with other  qualified persons,  the
                                       researcher must rigorously examine each question in the draft instrument.
                                   7.  Pre-testing: The revised draft must be pre-tested in order to identify the weaknesses of the
                                       instrument and to make the required further revisions to rectify them.
                                   8.  Specification of procedures/instructions: After the instruction is finalised after pre-tests,
                                       the procedures or instructions, relating to its use must be specified.
                                   9.  Designing the  format: The format should be suited  to the needs of  the research.  The
                                       instrument should be divided into different sections relating to the different aspects of the
                                       problem.

                                   Question Construction

                                   A survey instrument — interview schedules or questionnaire — is useful for collecting various
                                   types of information, viz., (a) factual information - facts about the respondents: sex, age, marital
                                   status, education, religion, caste or social class, income and occupation; and facts about events
                                   and circumstances,  (b) psychological information such  as attitudes, opinions,  beliefs,  and
                                   expectations, and (c) behavioural information, like social participation, and so on.
                                   Once the information need  is determined  as explained  in the previous topic, we can  begin
                                   question construction. This involves four major decision areas. They are: (a) question relevance
                                   and content, (b) question wording, (c) response form, and (d) question order or sequence.

                                   Question Relevance and Content

                                   My question to be included in the instrument should pass certain tests. Is it relevant to the
                                   research objectives? Can it yield significant information for answering an investigative question?
                                   If not, it should note be included in the instrument.

                                   Question Wording

                                   This is a difficult task. The function of a question in a schedule/questionnaire is to elicit particular
                                   information without distortion. “Questioning people”, says Oppenheim, “is more like trying to
                                   catch a particular elusive fish, by hopefully casting different kinds of bait at different depths,
                                   without knowing what goes on beneath the surface.” As the meaning of words differs from
                                   person to  person, the  question  designer  should  choose words which  have  the  following
                                   characteristics:
                                   a.  Shared vocabulary
                                   b.  Uniformity of meaning
                                   c.  Exactness
