Unformatted text preview: data consists of several public at different localities, the
sheets that are distributed in a specific locality may carry a unique part code
which is alphabetic. To this alphabetic code, a numeric code can be
attached to distinguish the person to whom the primary instrument was
distributed. This also helps the researcher to keep track of who the
respondents are and who are the probable respondents from whom primary
data sheets are yet to be collected. Even at a latter stage, any specific
queries on a specific responses sheet can be clarified.
Sikkim Manipal University Page No. 151 Research Methodology Unit 11 The variables or observations in the primary instrument would also need
codification, especially when they are categorized. The categorization could
be on a scale i.e., most preferable to not preferable, or it could be very
specific such as Gender classified as Male and Female. Certain
classifications can lead to open ended classification such as education
classification, Illiterate, Graduate, Professional, Others. Please specify. In
such instances, the codification needs to be carefully done to include all
possible responses under “Others, please specify”. If the preparation of the
exhaustive list is not feasible, then it will be better to create a separate
variable for the “Others please specify” category and records all responses
Numeric Coding: Coding need not necessarily be numeric. It can also be
alphabetic. Coding has to be compulsorily numeric, when the variable is
subject to further parametric analysis.
Alphabetic Coding: A mere tabulation or frequency count or graphical
representation of the variable may be given in an alphabetic coding.
Zero Coding: A coding of zero has to be assigned carefully to a variable. In
many instances, when manual analysis is done, a code of 0 would imply a
“no response” from the respondents. Hence, if a value of 0 is to be given to
specific responses in the data sheet, it should not lead to the same
interpretation of ‘non response’....
