Coding analysis steps

Coding analysis steps	Complete the task
1. open coding analysis	Conduct initial organization, parsing, and extraction of the original corpus, extract and define concepts from it, and then categorize the concepts.
2. axial coding analysis	Based on the results of open coding, further analyze the intrinsic connections between the initial categories, identify their hierarchical relationships, and gradually extract the main categories through continuous clustering and naming.
3. selective coding	On the basis of open coding and axial coding, combined with the core category of research, further determine the relationship between the main category and the core category.
4. Theoretical saturation test	Theoretical saturation refers to the analysis of new raw data that no longer generates new concepts and categories, as well as relationships between categories, in order to verify the reliability and consistency of the results of the three-level coding analysis.
