The history of probability random sampling was developed since from 60 to 70 years. Kiar from Norway was the advocate of sampling by the purposive method (non-probability random sampling) predominated Probability random sampling.... Purposive sampling represents a group of different non-probability sampling techniques. Also known as judgmental , selective or subjective sampling, purposive sampling relies on the judgement of the researcher when it comes to selecting the units (e.g., people, cases/organisations, events, pieces of data) that are to be studied.

A crucial feature and by-product of probability sampling in surveys is that sampling errors can be estimated from the data collected from the sample cases, a feature that is not mathematically justifiable when non-probability sampling methods are used....I have a few concerns here as the methodology used for the purpose of this study may score low on external validity and, therefore, making a conclusion based on non-probability (convenience sampling in this case) sampling may not be correct. This keeping in view the fact that the two institutions chosen for the purpose of this study are not actually representative of institutions across India

Karakteristik mungkin pantas dipertimbangkan dalam situasi jika ketelitian bukanlah kritis arti penting. 9Non-Probability sampling biasanya dapat dilakukan dengan cepat dibanding probability sampling
- a method of sampling that uses some form of random selection; every member of the population must have the same probability of being selected for the sample - since the sample should be free of bias and representative of the population
- In probability sampling, each member of the population has a known probability of being selected. In non-probability sampling, each member of the population is selected without the use of probability.
- In probability sampling, each population member has a known, non-zero chance of participating in the study. Randomization or chance is the core of probability sampling technique. Randomization or chance is the core of probability sampling technique.
