Samples

- what is a sample? It's something you use to figure out something without using everybody or everything.


- why take a sample? So you can know something without getting everything. Because it would take too long and it can cost too much to test everything.

- what are some examples of sampling done irl? Hospitals, the Police, the Government.


- what does the word ‘population’ mean? Every single thing or person
