Study Notes
Sampling in Qualitative Research
- The aim of sampling in qualitative research is to select a subset of participants that can provide rich, detailed, and insightful data to answer the research question.
Validity of a Research Project
- A vital component of the validity of a research project is the sampling strategy, which can affect the credibility and trustworthiness of the findings.
Sample Size in Qualitative Inquiry
- The sample size in qualitative research is determined by the concept of data saturation, which occurs when no new information or themes emerge from the data.
- The sample size (N) depends on the research question, study design, and the researchers' judgment of when data saturation is reached.
Sampling Process
- The process of sampling in qualitative research involves purposive sampling, where participants are selected based on their ability to provide in-depth information about the research topic.
Comparison between Qualitative and Quantitative Research
- The main difference between sampling for qualitative and quantitative research is the focus on depth versus breadth, with qualitative research seeking rich, detailed data from a smaller sample, and quantitative research seeking to generalize to a larger population.
Considerations for Sampling
- Considerations for sampling in qualitative research include the research question, study design, population, and the need to achieve data saturation.
Factors that Determine Sample Size
- The factors that determine the sample size in qualitative inquiry include the research question, study design, and the point at which data saturation is reached.
Data Saturation
- Data saturation is the point at which no new information or themes emerge from the data, indicating that the sample size is sufficient.
- The significance of data saturation is that it ensures that the data is comprehensive and that the research findings are reliable.
Sample Size in Qualitative Research
- Sample sizes are typically smaller in qualitative research compared to quantitative research because the focus is on depth and richness of data rather than breadth and generalizability.
- The primary reason for justifying small sample sizes in qualitative research is the achievement of data saturation.
Role of Data Saturation
- The role of data saturation is to determine the endpoint of data collection, ensuring that the data is comprehensive and that the research findings are reliable.
Critique of Data Saturation
- Data saturation has been subject to critical discussion due to concerns about the arbitrary nature of determining when data saturation is reached.
Size and Scope of a Sample
- The size and scope of a sample in qualitative research determine the depth and richness of the data, which in turn affects the validity and reliability of the research findings.
