A sample is where you get a small amount of something.

We take a sample to collect data and to get information in small amounts.

For example you would take samples of different blood types, food, and more so it will be less expensive and it wont take as much time.

You can tell you are sampling the right population by having a mixture of people also called random sampling, there are two types of random sampling fair and byist.

There are two types of sampling fair and biased.

some examples of irl sampling are when you take a blood test or when you test food to see if it tastes good, drug testing.
