Supplementary material - Toward Effective Educational Supervision in Yemen-A Hybrid Fuzzy Delphi and Clustering Analysis of Technical Barriers

The file includes all extended data and processing results related to the study "Toward Effective Educational Supervision in Yemen: A Hybrid Fuzzy Delphi and Clustering Analysis of Technical Barriers." This file integrates the application of the Fuzzy Delphi method to assess the consensus and suitability of the items, validated by 16 experienced educational experts. It also contains the collected and processed data from a quantitative survey targeting 370 teachers, along with the Fuzzy Set Theory processes for data aggregation.Additionally, it illustrates the K-means clustering results for segmenting the barriers based on their impacts. All this data is merged into a single Excel-based tool. This source also includes the values underlying the results reported, as well as the data used to construct tables and figures in all analysis and discussion sections.This supplementary resource provides detailed support for replicating the study’s methods and results.
