When we subsample from a population

Explanation:

A subsample is a set of data that we take from smaller group of people in order to represent the larger group.

It is really crucial for companies to get this type of subsample in order to obtain statistical data about customer's preference. This will increase the efficiency of their marketing process.

For example,

Let's say that you want to create a toy for children.

It is impossible for you to actually ask every single child in this country about the type of toys they like. In such situation, you could get a subsample from a smaller group of children (let's say you give questionnaires to 1000 children and ask them the type of toys they like.)

From the there, you could create a statistic that represent the types of toys that the children might be interested in.
