Population, Sample and Sampling

​Population

The population refers to the totality of objects, elements, person and characteristics under a given condition. In other words, population refers to the entire group that you want to draw conclusions about

​Sample

Sampling is the process of technique of choosing a sample from a population to participate in the study.

​

Sampling​

A. Convenience sampling

​Convenience sampling is defined as a method adopted by researchers where data is collected from a conveniently available pool of respondents. It is the most commonly used sampling technique as it’s incredibly prompt, uncomplicated, and economical. In many cases, members are readily approachable to be a part of the sample.

B. Snowball sampling

​Snowball sampling or chain-referral sampling is defined as a nonprobability sampling technique in which the samples have rare traits. This is a sampling technique, in which existing subjects provide referrals to recruit samples required for a research study.

C. Quota sampling

​Quota sampling is defined as a non-probability sampling method in which researchers create a sample involving individuals that represent a population. Researchers choose these individuals according to specific traits or qualities. These samples can be generalized to the entire population. The final subset will be decided only according to the interviewer’s or researcher’s knowledge of the population
