Question

Consider the population of employees of a large international corporation. Which of the following would represent a cluster sample of the population?

a) Selecting every 5th employee from a list of all employees.
b) Randomly selecting employees from different divisions.
c) Surveying employees who work on the same floor of a building.
d) Choosing employees based on their job titles.

Answer 1

Surveying employees who work on the same floor of a building would represent a cluster sample.

Step-by-step explanation:

A cluster sample involves dividing the population into clusters or groups and then randomly selecting some of the clusters to form the sample. In this case, surveying employees who work on the same floor of a building (option c) would represent a cluster sample. All the employees on that floor would be included in the sample. This is different from other options like selecting every 5th employee (option a), randomly selecting employees from different divisions (option b), or choosing employees based on their job titles (option d).
