Role of Subjectivity in Preparation of Sampling Frames for Data collection.

"Collection of data from the field on various socio-economic aspects is consisting of several stages. Stratification of the population into required numbers of stratum (if it is heterogeneous) and the selection of sample units from each stratum on the basis of various random sampling method are precondition for scientific collection of data from a particular sample unit and therefore preparation of a scientific Sampling Frame which is the basis of selection of required number of sample units is of utmost importance. The established scientific procedure needs to be followed strictly while preparing the Sampling Frame and any subjectivity may enhance the sampling error to a great extent. An attempt has been made in this study to highlight the issues relating to the preparation of sampling frame in a Multistage Stratified Socio-Economic Survey and the role of subjectivity thereof."
