Answer

A random sample is a sample drawn in such a way that each element of the population has some chance of being selected in the sample. A nonrandom sample is a sample in which some elements of the population are more likely to be selected than other members. In a convenience sample, the most accessible members of the population are selected to obtain the results quickly. In a judgement sample, the members are selected from the population based on the judgment and prior knowledge of an expert. In a quota sample, the population is being divided into different sub-populations based on certain characteristics, then a sub-sample is being selected to represent the sample in exactly the same proportion as in the target population.
