In quota sampling, the researcher aims to represent the major characteristics of the population by sampling a proportional amount of each. For example, if you wanted to obtain a proportional quota sample of 100 people based on gender , you would need to start with an understanding of the man/woman ratio in the larger population.

Non-probability sampling techniques include convenience sampling, snowball sampling and quota sampling. In these techniques, the units that make up the sample are collected with no specific probability structure in mind. The selection is not completely randomized, and hence the resultant sample isn’t truly representative of the population. Research studies are usually carried out on sample of subjects rather than whole populations. The most challenging aspect of fieldwork is drawing a random sample from the target population to which the results of the study would be generalized. In actual practice, the task is so difficult that some sampling bias occurs in almost all studies to
