Me with this ! members of a polling organization survey 700 of the 7,453 registered voters in a town by randomly choosing names from a list of all registered voters. is their sample likely to be representative?

Most likely not.

The reason behind this is that the random participants only include just under 10% of the population. This has the ability to oversee minority judgement.

Cluster sampling should be used. This splits the population up into groups. For instance, we could split it up by race and sample that way. Or split it up by net worth. Or occupation. Whatever works best for this survey!

Hope I helped!
