6. Training of data collectors and supervisors
Data collectors and supervisors must be given explicit training. Their training should be
supported by practical exercises. They should be involved in the pretest. Following the

pretest, they could participate in the adjustment of instruction sheets and data-collection
tools.
During the training, the data collectors and supervisors should be strongly instructed that they
would be responsible for any mistakes that may arise due to their negligence and lack of
adherence to the manual.
7. Conducting pretest in the research location (nearby area) and revising data-
collection tools
• The pretest should assess the validity of the data-collection instruments and
procedures, as well as the sampling procedures
• It should identify scientific as well as logistical problems and constraints
• Revise the data-collection tools and other procedures after the pretest
8. Data collection
After getting permission for the conduct of the study, obtained the necessary resources,
trained the required personnel, made pretests and modified data-collection tools and
procedures, the required data collection can be carried out.
9. Processing data
After collecting and sorting the data, all questionnaires and records should be checked for
errors. This should be done before leaving the area where data collection is done. If there is
any error to be corrected regarding a particular questionnaire, it would be easy for the data
collector or supervisor to make the changes by visiting the respondent from which the
information was obtained.
During this stage, answers given for open-ended questions may be converted into
quantifiable numerical form for processing by computer or other means.
