| Quality control measures
are often put in place to ensure that valid and reliable data are
obtained from the field. Although, there are general guidelines, the
peculiarities of a particular study will inform specific control to be
adopted. However, the following represents the basic measures of
control: |
• Comprehensive briefing and
training of all field personnel on the scope, modality and demand of
study.
• The group interview method is usually adopted in a survey in order to
enhance compact supervision, thereby eliminating incidence of fraud and
this also allows for immediate on-the-spot check/editing of
questionnaires.
• Interviewers are trained to be sensitive to the norms and mores of the
average Nigerian society in a local setting. To this end, efforts are
made to use interviewers who are resident in each town/locality and who
speak local language of relevance.
• Interviewers are to assure respondents of complete anonymity and shall
treat all responses as confidential.
• Field coordinators and Quality Control managers are expected to
back-check at least, 20% of achievements during field work, usually
adopting the multi-supervisory-level approach.
• Aside editing on field, completed questionnaires are also edited in
the office. This is prior to listing of responses [in case of open-end
questions], followed by classification into compatible groupings to form
the coding frame.
• Coding and editing is usually done by our trained hands under the
supervision of the executive in charge of the project and a senior field
supervisor.
• Analysis and reporting is done by the project director, in conjunction
with other executives in the team.
