Election polls: Predictive Analytics at its most exciting

  1. It’s unfortunate that many poll survey results, even by reputed analysts, are not supported with the sample size, sampling method, confidence level, and the margin of error.

    I am not sure why these companies used such a very large sample size (40,000 to 160,000) and how they ensured randomness is anyone’s guess.

    It would be better if the analysts or researchers supply these meta-data of such public surveys conducted to enhance the trustworthiness among the public of such socially important reports.
