Study Notes
Sampling in Quantitative and Qualitative Studies
- Most empirical studies use some form of sampling.
- In quantitative studies, the primary use of sampling is to create a representative sample of a larger population.
- In qualitative studies, sampling is used to deepen understanding about a larger process, relationship, or social scene.
Reasons for Sampling
- Sampling is used in both quantitative and qualitative studies to:
- Create a representative sample of a population.
- Deepen understanding about a larger process, relationship, or social scene.
Strategies for Creating a Representative Sample
- Probability sampling:
- Uses reasoning and applied mathematics.
- Is the preferred method for creating a representative sample.
- Non-probability sampling:
- Convenience sampling:
- Uses easily accessible cases.
- Is not recommended for creating an accurate sample.
- Quota sampling:
- Involves selecting cases based on specific criteria.
- Is used to create a representative sample.
- Convenience sampling:
Probability Sampling Techniques
- Random sampling:
- Involves randomly selecting cases from a population.
- Is the most likely method to represent the entire population.
- Six ways to sample randomly:
- Simple random sampling
- Sampling distribution
- Central limit theorem (CLT)
- Confidence interval
Deciding the Sample Size
- Two methods:
- Make assumptions about the population and use statistical equations about random sampling processes.
- Use a rule of thumb (a conventional or commonly accepted amount).
- The smaller the population, the larger the sampling ratio has to be for a sample that has a high probability of yielding the same results as the entire population.
Strategies for Non-Representative Samples
- Five nonrepresentative sampling techniques:
- Purposive or judgmental sampling
- Linked-traced sampling
- Snowball sampling
- Respondent-driven sampling
- Adaptive sampling
- Deviant case sampling
- Sequential sampling
- Theoretical sampling
