This notebook continues the analysis of the World Bank Statistical Performance Indicators (SPI) dataset, a longitudinal country-level dataset covering 217 countries from 2004 to 2023. Each row represents one country-year observation and includes multiple measures of statistical capacity, such as data use, data products, and infrastructure. Building on the hypothesis testing work from Week 7, this analysis shifts toward modeling. Two questions are addressed. First, does income group explain differences in overall statistical performance across countries? This is tested using a one-way ANOVA. Second, can a single continuous sub-indicator, data_products_score, predict a country's overall performance? This is explored through simple linear regression. These two approaches move beyond comparing group means toward understanding the structure of the relationship between statistical capacity indicators.
