Option 3 : Purposive sampling

Concept:

Sampling is a process of selecting predetermined number of observations from a larger population
Majorly we have 2 types probability and non probability sampling techniques
Probability sampling technique includes
- Simple random sampling
- Cluster random sampling
- Systematic random sampling
- Stratified random sampling
Non probability sampling technique includes
- Convenience sampling
- Judgmental or purposive sampling
- Snowball sampling
- Quota sampling

In probability sampling all the members will have an equal opportunity to participate in research
In non probability sampling researcher selects the samples randomly where all the participants may not get equal chance to participate in study
Systematic sampling in this the researcher chooses the sample members of a population at regular intervals
In stratified random sampling the researcher divides the population into small groups which represents the larger group
Purposive sampling method researcher purely consider the purpose of the study along with the understanding of audience
