We are asked to complete the following sentence.
A(n) ? is part of population. |
Let's recall that, in statistics, a population is all members of a group of interest. In other words, a population is all of the people about which we are looking for information. In some cases, it would be difficult for us to ask every person in our population. This is why we usually use a part of the population, which is called a sample.
Here are a few examples of populations and possible samples from each one.
Population | Sample |
---|---|
The population of the U.S.A. | A randomly chosen 100 thousand U.S. citizens |
The population of the student body | All of the people from your class |
All potential consumers of a new product | Volunteers that want to fill out a survey |
Now we are able to complete the sentence.
A sample is part of population. |
