"Random" Sampling and "representative" Sampling
In standardized jury research, which draws on a pool of research jurors who are limited to a single venue, quickly locating and securing the services of jurors with such ideal characteristics can be a daunting if not impossible task. This is why standardized jury research often is conducted instead on the basis of "random" sampling (based on lists derived through voter registration, driver license applications, and so on); or through "representative" sampling (based only on demographic characteristics - age, ethnicity, sex, and so on). However, these much less refined methodologies do not present the same type of scientifically valid and meaningful research results that can be achieved through stratified sampling. But with the Internet, and its hundreds of millions of users worldwide, stratified sampling is not a problem; hence the value of virtual jury research in comparison to more standardized formats.

Famous quotes containing the word random:
“Assemble, first, all casual bits and scraps
That may shake down into a world perhaps;
People this world, by chance created so,
With random persons whom you do not know—”
—Robert Graves (1895–1985)
