Answer

Brief Explanations:

  1. Separating students by grade level and selecting from each is stratified sampling as the population is divided into strata (grade - levels).
  2. Pulling names from a hat is simple random sampling where each name has an equal chance of being selected.
  3. Surveying every 3rd driver is systematic sampling as it follows a fixed - interval pattern.
  4. Dividing by voting precinct and sampling everyone in selected precincts is cluster sampling where precincts are clusters.
  5. Asking 20 closest friends is convenience sampling as it is based on ease of access.

Answer:

  1. a. Stratified
  2. e. Simple Random
  3. d. Systematic
  4. c. Cluster
  5. b. Convenience
