Sampling a Population

What is a population?

A population is a group or collection of things. The population of your city or town is the group of people who live there.

Sometimes, a population is too big to study or too hard to count. Then you study a sample of the population. A sample is a smaller group or part of the whole population.
Say you want to learn about the population of pets in your town. You can begin by counting the number of dogs, cats, birds, and other pets on your block.

Using this information, you can predict the kinds of pets that people have in your town.

You can also use your data to predict which pet is the most common in your town or neighborhood.
