This project demonstrates how a wide-format dataset can be cleaned and transformed into tidy format using the tidyverse in R. A global country dataset containing economic, health, and demographic indicators was standardized, reshaped using pivot_longer, and analyzed to explore relationships between key variables. The analysis focuses on examining the relationship between GDP and life expectancy across countries through summary tables and visualizations.
