Advantages of cluster sampling include that it's inexpensive, fast, and simple. A disadvantage is that it is known to have a high sampling error.
Sampling techniques in researching involves to types of sampling. The probability sampling and the non-probability sampling. Simple random is an example of probability sampling.
Advantages and disadvantages of probability sampling: Advantages: Since it is done at random, the whole process is unbiased. This is good to use in smaller populations, of course it doesn't 100% protect from bias (depending on the question). But this option is a quicker way of achieving information. Disadvantages: As i said before, depending on your question it cannot prevent from bias. Also, if you are sampling information from a large population this will take too much time and patience. There is also no guarantee that what these people say, represents what another group of people believe. Non-probability sampling: Advantages: This is more accurate because you are targeting a specific group, therefore your answers will be similar to what the rest of the population (of this group) will answer. Disadvantages: This is more biased, because the individuals chosen are not at random. They also might not represent what another population thinks
the difference is just that non-probability sampling does not involve random selection, but probability sampling does.
Non probability sampling and probability sampling are different because probability sampling uses random samples. Non probability sampling aren't random, but can still be representative of the population as a whole if done correctly.
