Question

Research question: Are employees at one large company satisfied with their health insurance? Sample method: A list of the 15,234 employees at the company is obtained. A random number generator is used to select the names of 25 employees to participate in a survey study. What type of sampling method was used

Answer 1

Systematic random sampling

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.

Answer 2

The random sampling method was used.

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.
