When the Bureau of Labor Statistics conducts a survey, it begins by partitioning the United States adult population into 2,007 groups called primary sampling units. Assume that these primary sampling units all contain the same number of adults. If you randomly select one adult from each primary sampling unit, is the result a simple random sample?

Respuesta :

Using sampling concepts, it is found that since the population is divided into groups, it is a stratified sample, not a simple random sample.

Samples:

Samples are classified as:

  • Convenient: Drawn from a conveniently available pool.
  • Random: All the options into a hat and drawn some of them.
  • Systematic: Every kth element is taken.  
  • Cluster: Divides population into groups, called clusters, and each element in the cluster is surveyed.
  • Stratified: Also divides the population into groups. However, only some elements of each group are surveyed.

In this problem, the population is divided into 2007 groups, and one element from each group is surveyed. Since the population is divided into groups, it is a stratified sample, not a simple random sample.
