Fatal problem of using the public opinion polls or questionnaires

1 minute read

Published:

Fatal errors pierce into results of the opinion polls while set p = 0.5 and use the property of thecentral limit theorem since (1) the approximating continuous distribution does not mean the “real” continuous distribution, (2) the minimal sample size of the central limit theorem does not be tested, but the theorem is applied, and (3) there is no test for the probability under the specific p and sample size.

This post shows the evidecne at the case of p = 0.5. Mail me to obtain more evidence of other p. Seek the coorperation to write papers. Mailing me.
