Statistical analysis of Tunisia's education & development indicators (2000–2022) using hypothesis testing, OLS regression, and correlation analysis. Data sourced from World Bank Open Data API. # Education Investment & Human Development in Tunisia ## A Statistical Analysis (2000–2022) --- ## Abstract This study examines the relationship between education investment and human development outcomes in Tunisia over the period 2000–2022. Using five World Bank indicators — education expenditure (% of GDP), GNI per capita, adult literacy rate, unemployment rate, and secondary school enrollment — we apply Pearson correlation analysis, OLS regression, and Welch's t-tests to assess whether public spending on education is a statistically significant predictor of economic and social development. Our findings suggest a moderate-to-strong positive association between education expenditure and GNI per capita, while significant structural breaks are observed around 2010–2011, coinciding with the Tunisian Revolution. --- ## Table of Contents - Research Question - Dataset - Methodology - Results - Descriptive Statistics - Hypothesis Testing - Regression Analysis - Correlation Analysis - Visualizations - Conclusions - Limitations - How to Run - Project Structure - References --- ## Research Question > **Does public investment in education predict human development outcomes in Tunisia?
