Ashocking fact: 66% of all teenagers have a tv set in their room. if an opinion poll chooses an srs of 1000 teens and asks if they have a tv set in their room, the percent who say "yes" will vary if the sampling procedure is repeated. but the distribution of the percent who say "yes" in all the samples is centered at the truth about the population (66%). we call this desirable characteristic of sample proportions a low variability. b statistical significance. c sample repeatability. d absence of bias. e symmetry.

Answer – D. (Absence of bias)

The fact that the distribution of the percent of teens who say "yes" in all the samples is centered at the truth about the population (66%) shows the absence of bias in the Systematic Reviews (SRs). Lack of bias is a desirable characteristic of sample proportions as it lends to its reliability.
