1. Convenience Sampling:
- Advantages: Easy and quick to implement, cost-effective, useful for exploratory research or when access to a specific population is limited.
- Disadvantages: Results may not be representative of the population, potential for bias as participants self-select to participate.
2. Snowball Sampling:
- Advantages: Useful for hard-to-reach populations, can access hidden populations, cost-effective.
- Disadvantages: Potential for bias as participants refer others who are similar to them, may not be representative of the population.
3. Quota Sampling:
- Advantages: Allows for representation of different subgroups within a population, relatively quick and cost-effective.
- Disadvantages: Requires prior knowledge of the population to set quotas, potential for bias if quotas are not set appropriately.
4. Purposive Sampling:
- Advantages: Allows for selection of specific participants who have relevant knowledge or experience, useful for in-depth qualitative research.
- Disadvantages: Results may not be generalizable to the larger population, potential for researcher bias in selecting participants.
5. Judgmental Sampling:
- Advantages: Allows for selection of participants based on the researcher's judgment of who is most relevant, useful for specialized populations.
- Disadvantages: Results may not be representative of the population, potential for bias in the researcher's judgment.
