Black Americans Lead Whites in Getting Vaccinated By Double Digits in New Poll

[praxEs]

68. Unfortunately the number of Black respondents (130) among the 1000

persons sampled overall is just plain too small to provide any trustworthy basis for estimating the population parameter of the vaccination rate for all Black people in the US. It's not really the self-report that is problematic. Note that almost all polls of human beings' verbal responses are self-report and there is little sound basis for estimating that Black respondents would dissemble at a rate that might differ from white folks' level of misrepresentation.

Have you ever encountered a poll that purported to characterize an entire population or subpopulation of the US on the basis of N = 70?

You have not.

Nor have I.

The most primitive statistical notions involving the use of a sample statistic to estimate a population parameter are presented in the first few weeks of a semester long, elementary statistics course. Such courses occur frequently now in high school curricula.
