This project is a Decision Support System designed to analyze the Turkish General Social Survey (TGSS-2024). It bridges the gap between complex statistical data and executive decision-making by using Machine Learning to identify the "Root Causes" of social trends.
Why this matters: In a world of "thorny business challenges," simply seeing data isn't enough. This tool identifies the North Star metrics of social indicators and provides synthesized recommendations.
- Predictive Modeling (Root Cause Analysis): Utilizes Random Forest algorithms to determine feature importance—identifying exactly which variables (age, income, education, etc.) most significantly impact social outcomes.
- Automated Executive Insights: A custom-built "Expert Commentary" module that translates statistical correlations into human-readable business language.
- Dynamic Data Pipeline: Seamlessly handles SPSS (.sav) metadata, mapping complex survey labels to intuitive interactive dashboards.
- Impact Simulation: Allows users to visualize how shifts in specific demographics could influence overall social satisfaction metrics.
- Engine: Python 3.x
- Analysis: Pandas, NumPy, Scikit-Learn (Random Forest Regressor/Classifier)
- Frontend: Streamlit (Interactive Web UI)
- Visualization: Plotly Express for high-fidelity interactive charting
- Data Source: Turkish General Social Survey (TGSS-2024)
- Extraction: Cleaning and preprocessing high-dimensional survey data.
- Modeling: Training a Random Forest model to rank "Predictor Importance."
- Synthesis: Zooming out from raw coefficients to develop compelling, synthesized recommendations for policy-makers and stakeholders.
I was introduced to the TGSS-2024 dataset during the Data Analysis School, organized by the Council of Higher Education (YÖK) and the Institute of Population and Social Research. This project aims to bring a modern, AI-driven perspective to the valuable data provided by these institutions.
