Sampling is the technique which used to take sample from the population. There are two types of sampling methods, they are probability and non probability sampling. Probability sampling involves random assumption of all the observation in the population can involve in the sample. Non probability sampling does not provide equal chances to all the observation in the population to involve in the sample.
