**Understanding Sampling Methods in Surveys**

**Scenario:**

An airline wants to assess customer satisfaction by choosing a random sample of 10 of its flights during a single month. Then, they ask all of the passengers on those flights to fill out a survey. This type of sampling is an example of:

(a) multistage sample.
(b) stratified sample.
(c) cluster sample.
(d) simple random sample.
(e) convenience sample.

**Explanation:**

In this context, the airline is employing a **cluster sample**. The airline randomly selects entire flights (clusters) and then surveys all passengers on those flights. This method is efficient because it collects feedback from entire groups at once and is often used when the population is naturally divided into groups, such as flights in this case.

Expert Solution

Step 1

In cluster sampling, the population is divided into naturally occurring groups/sections called clusters. Some of these clusters are selected randomly for the sampling and all the units are taken from these randomly selected clusters to study.

In this case, the airline randomly selects 10 flights in a month, and then surveys every passenger in the selected flights. Clearly, this is an example of cluster sampling and the sample can be considered as cluster sample.
