| NBA Player Performance Analysis (1990–2024) | |
| This project analyzes NBA player performance trends from 1990 to 2024 using season-level data. The goal was to clean, explore, visualize, and interpret long-term changes in scoring, assists, 3-point shooting, and player height. The dataset was filtered to include only NBA players, and the selected features were Season_Year, PTS, AST, 3PM, and height_cm. After cleaning, the final dataset contained 7,633 rows and 6 columns. | |
