Summary
Theoretical sampling is crucial for grounded theory. This method guides data collection and analysis to build robust theory, even in secondary data analysis.
Area of Science:
- Qualitative Research Methods
- Grounded Theory Methodology
- Social Sciences Research
Background:
- Theoretical sampling is essential for theory development in grounded theory.
- Researchers often face challenges in applying theoretical sampling correctly.
- Existing literature may not fully clarify its function and distinctiveness.
Purpose of the Study:
- To clarify the application and function of theoretical sampling in grounded theory.
- To differentiate theoretical sampling from sampling solely for data generation.
- To illustrate its role in theory building, concept development, and secondary analysis.
Main Methods:
- Illustrating theoretical sampling in diverse grounded theory studies.
- Answering key researcher questions regarding theoretical sampling.
- Demonstrating the interplay of induction, retroduction, abduction, and memoing.
- Applying theoretical sampling within secondary data analysis.
Main Results:
- Theoretical sampling actively guides the iterative process of data collection and analysis.
- It differs from sampling for data generation by focusing on theory development.
- Memoing is integral to driving theoretical sampling and concept formation.
- Theoretical sampling enables theory derivation in secondary analysis.
Conclusions:
- Theoretical sampling is a dynamic process integral to grounded theory.
- It facilitates contextualization of data for robust concept and theory construction.
- Its application extends to secondary analysis for novel theory generation.
- Clear understanding enhances the rigor and utility of grounded theory research.

Sampling is a crucial step in analytical chemistry, allowing researchers to collect representative data from a large population. Common sampling methods include random, judgmental, systematic, stratified, and cluster sampling.
Random sampling is a method where each member of the population has an equal chance of being selected for the sample. It involves selecting individuals randomly, often using random number generators or lottery-type methods. For example, when analyzing the properties of a...

01:16Stratified Sampling Method
14.4K
Sampling is a technique to select a portion (or subset) of the larger population and study that portion (the sample) to gain information about the population. The sampling method ensures that samples are drawn without bias and accurately represent the population. Because measuring the entire population in a study is not practical, researchers use samples to represent the population of interest.

A sample refers to a smaller subset representative of a larger population. In analytical chemistry, studying or analyzing an entire population is often impractical or impossible. Therefore, samples are used to draw inferences and generalize the whole population. The sampling method selects individuals or items from a population to create a sample. Standard sampling methods include random, judgemental, systematic, stratified, and cluster sampling.

Appropriate sampling methods ensure that samples are drawn without bias and accurately represent the population. Because measuring the entire population in a study is not practical, researchers use samples to represent the population of interest.
To choose a cluster sample, divide the population into clusters (groups) and then randomly select some of the clusters. All the members from these clusters are in the cluster sample. For example, if you randomly sample four departments from your...

Sampling is a technique to select a portion (or subset) of the larger population and study that portion (the sample) to gain information about the population. Data are the result of sampling from a population. The sampling method ensures that samples are drawn without bias and accurately represent the population.
