Demystifying The Ubiquitous Sample Size Of 2000

  @Melvin Haskins:  Thank you for your comment.  As I pointed out in the original post, "A nation tends to be homogeneous on some parameters (e.g. nationality) ..." A survey of 2K people each in New York and Wyoming will show that a majority of them are American citizens, with the minority comprising tourists, immigrants on H1B, F1, Green Card but not US passports. Regardless of the diversity of population between these two states, this finding will be correct for both states.  OTOH, someone can counter that by saying, we really don't need a survey - of whatever size - to reach that motherhood conclusion.  So, in addition to the last paragraph, one more key thing that determines the validity of survey findings based on a particular sample size is, what is the characteristic being surveyed and whether it's deep enough to require a survey at all.  IMO, the other important factor is, is there a rigorous quantitative measure of representativeness of sample and homogeniety of population. I've reached out to at least 10 people, including a couple of people with degrees in Data Science, quizzing them on this point. I haven't received a single reply.   Intrigued, I looked up my 30 year old MBA text book on quant methods. It says this subject lies at the heart of the objectivist-subjectivist controversy and no definitive answer can be given on it. I didn't bother to go back to my 35 year old philosophy (Humanities elective during Engineering, if you want to know!) text book to figure that one out.   Someday, I hope I can provide a more definitive perspective on this subject but, as of now, my blog post has to end on a note of suspense!

  Your very last paragraph is the most important. Whilst the USA has a population of 330 million in 50 states, there is no comparison between the people of New York and of Wyoming. They may be in the same country but their values, habits and lifestyles will be very different. Any survey of 2,000 in the USA has no chance of reflecting the diversity in the country.
