Sampling is the process of s<u>electing individuals or smaller groups from a larger population</u> to act as <u>representatives of that population.</u> This is used to make statistical assumptions and infer the traits of the population as a whole.
Sampling techniques can be divided into many categories and subcategories. There are four main forms of sampling, which include:
- Simple random sampling.
- Systematic sampling
- Stratified sampling
- Cluster sampling
Each of these can then be divided further.
Sampling techniques can sometimes be random, <u>intended to avoid biased choices that benefit the achievement of the desired result</u> and therefore render the conclusion inaccurate. This is the biggest weakness in sampling methods. Errors in sampling can lead to <u>false assumptions and misleading data. </u>
