Question

A television station plans to send a crew to a polling center on an election day. because they do not have time to interview each individual voter, they group voters by race. next , they select several of these groups by using a lottery and ask every voter, from the selected groups, for an interview. what type of sampling is this

Answer 1

The described sampling method where voters are grouped by race and a few groups are selected for interviews through a lottery is known as cluster sampling.

Step-by-step explanation:

The type of sampling described is cluster sampling. In this method, the television station is grouping voters by race, and these groups serve as 'clusters'. A lottery is then used to select which clusters to interview, and every voter within the selected clusters is asked for an interview. This two-stage process is characteristic of cluster sampling, where the first stage involves forming clusters and the second stage includes randomly choosing which clusters to assess.
