## Definition

Sampling technique is a process of selecting people  or a subset of the given population. It is done to make inferences and characterize the whole population.

## Summary

• Sampling technique plays an important role in research.
• It is a part of a research work which requires thorough preparation and planning.
• Researchers do not just select a group of people without basis.
• Selecting inappropriate sample will reflect in the final results of the study.

TYPES OF SAMPLING

Probability Sampling – It is a sampling method that utilizes a random selection. Each individual or element is given an equal chance of being selected as a sample.
Non-Probability Sampling – It is also known as the non-random sampling where not all elements of the population has a chance of being selected as a sample.

TYPES OF PROBABILITY SAMPLING

Simple Random Sampling – Every element is selected randomly and has an equal chance. Tools like random generators or the like can be used.
Stratified Random Sampling – Sample is selected by dividing the group into small subgroups (strata) based on the common characteristics and sample is selected from the strata.
Systematic Sampling – Every element is selected randomly from a starting point and then select every nth element in the population or a regular interval.
Cluster Random Sampling – This technique divides the population into groups called clusters and randomly selects members from the groups or clusters.

TYPES OF NON-PROBABILITY SAMPLING

Convenience Sampling – Sample is selected based on what is available or the convenience of the researcher.
Consecutive Sampling – This technique is more like a convenience sample but with little difference. In this method, the researcher will choose a person or group of people, conduct a research and collect results for a period of time, and will move to another sample.
Purposive Sampling – The samples in purposive sampling is selected based on the discretion or knowledge of the researcher and based on the objective of the study. This is also known as the judgmental, selective, or subjective sampling.
Snowball Sampling – This technique is also known as the chain-referral sampling technique. Snowball is used to select samples which have traits that are hard to find. Existing subjects in the population are asked to recruit more sample units which have the same traits of the targeted population.
Quota Sampling – In this technique, the researcher selects the sample based on specific attributes or traits. They decide and make quotas so that the sample will be useful to the research.
