Answer:
The random sampling method was used.
Step-by-step explanation:
Samples may be classified as:
Random: Basically, put all the options into a hat and drawn some of them.
Systematic: Every kth element is taken. For example, you want to survey something on the street, you interview every 5th person, for example.
Cluster: Divides population into groups, called clusters, and each element in the cluster is surveyed.
Stratified: Also divides the population into groups. However, then only some elements of the group are surveyed.
In this question:
Fro all the employees(15,234), 25 are chosen. The employees are not divided into groups.
So the random sampling method was used.
Answer:
Systematic random sampling
Step-by-step explanation:
With systematic random sampling, a list of every member of the population is created and from this list, we randomly select the first sample element from the first required elements on the population list.
This method of sampling is different from "simple random sampling" since every possible sample of the required elements is not equally likely.
