Research Methodology

[Bahni Mukhopadhyay]

Is 'sampling design' an essential part of 'research design', esp. in case of pure science research?

[Siddhartha Shankar Ray]

Dear Ms Bahni Mukhopadhyay,

Thanks for your post and for raising a serious and a rather unpopular issue in comparison to those which we often see in this forum! Sampling design is not always mandatory for Pure Science Research. Sampling is required in the case of field studies and SURVEY RESEARCH where number of population  becomes so huge that it is humanly not possible to cover each individual. However, for in-vitro research, each of the analysis (& observations) needs be taken into consideration.

There are various ways of sample size determination and random sampling methodologies and there are Chi square tests for determination of significance tests as well. You can get such materials in any statistical handbooks and even in the field of Library Sciences. In case you are serious  for further knowledge, I can refer you to some front line Scientific Research institutes in Calcutta where you can see by yourself about survey and in-vitro research.

Sincerely,

Siddhartha S. Ray, Calcutta

Thanks a lot Sir, for taking time out to give me a prompt reply. I'd like to first go through some text books. then, if required, i'd definitely ask you for the material/institutions you've suggested. Thanks again.

Dear Madam,

If you want to do scientific research and your population is so huge that you can't collect the data from whole population and use sample method, then the "sampling design" should be the essential part of your research design.
