Briefly describe the situation where Coding of the responses can be done before
the data collection and when coding is done after the data collection?
Coding before the collection of data:Whenever is possible the best way of processing is to begin before the actual survey is
carried out. Pre-coding is a procedure that applies to only close ended questions where
answers are few in numbers and predictable. This can be done when questions are highly
structured and only can have a few answers. It involves two operations, (1) attaching a
numerical value to each response, (2) designing a location for every item in the
questionnaire.
Coding after the collection of data:When questions are open ended and answers are not predictable the coding of data is
done after the data is actually collected. Categories in which responses are to be coded
must be established after examining that what respondent actually had to say?
In many cases, such as when researchers are using open-ended questions, a framework
for classifying responses to questions cannot be established before data collection. This
situation requires some careful thought concerning the determination of categories after
editing process has been completed. This is called post-coding or simply coding.
