In an astronomical context, an unbiased sample might consist of that fraction of a complete sample for which data are available, provided the data availability is not biased by individual source properties.

The probability of visiting each leaf is and this is identical for all of the ESU-Tree leaves; therefore, this method guarantees unbiased sampling of sub-graphs from the network.

Statistics classes spend entirely too much time on various formulae, and yet never seem to cover the basics like how to tell dependent events from independent or how to take an unbiased sample.

Despite the fact that this precinct is packed chock-full of minorities ( in fact there isn't a single straight white male in town ), here's a way to guarantee a statistically unbiased sample.
15.
With the correction, the unbiased sample variance is unbiased, while the corrected sample standard deviation is still biased, but less so, and both are still consistent : the correction factor converges to 1 as sample size grows.

Researchers and academics have not tried to collect a random unbiased sample of bullshit . ( I can see the grant proposal now . . . ) Bullshiters rarely admit the intention or goal of the bullshiting even if they are consciously aware of it.
17.
For example, the square root of the unbiased estimator of the population variance is " not " a mean-unbiased estimator of the population standard deviation : the square root of the unbiased sample variance, the corrected sample standard deviation, is biased.

Based on a taste test, usually of a piece of paper soaked in PTC ( or the less toxic dominant allele at a single autosomal gene, and that the class is an unbiased sample from a population in Hardy-Weinberg equilibrium, students then estimate allele and genotype frequencies within the broader population.
