(a) Non-Probability Sampling
This method involves choosing items from the population without using a random sampling technique. Elements in the target population have an unknown chance of being selected into the sample. A non-probability sample is based on subjective judgement and is biased in the sense that some members of the target population have more chances of being selected than others. There are three main types of non-probability sampling: quota, judgement and convenience.
(b) Probability sampling

There are many ways in which a probability sample may be drawn from a population. Some of these ways are described below.
