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.
