what is a sample? A small bit of the population so that you do not have to test the whole population. Use you a sample to find out something that is not using everybody and everything.
why take a sample? Because if you take all of say a blood example it could be harmful.
what does the word ‘population’ mean? It means everyone or things that you are testing.
how can you tell if are you sampling the right population? when you ask a different kind's of people not just the same kind of person in personality.
what are some examples of sampling done irl?
