Sampling is important because it is impossible to (observe, interview, survey, etc.) an entire population. When surveying, however, it is vital to ensure the people in your sample reflect the population or else you will get misleading results.
There are many methods through which sample can be selected to collect the data which is required for the investigation. Some of the methods are simple random, stratified, cluster sampling, systematic random sampling and so on.
