Explore a small dataset with spreadsheet, database, and Python demonstrations.
An orientation to three common ways to inspect tabular data, not a promise to master all three in one sitting. Four open-license demonstrations show an Excel project, MySQL setup, a SQL exploration, and cleaning with Pandas. Follow one path with a small dataset and document assumptions before moving to the others.
Inspect the shape and meaning of a small table. Choose between a spreadsheet, SQL, and Python for a simple question. Document a cleaning decision and a check on the final result.
Basic file management. Installation is optional for the first lesson; later demonstrations use MySQL and Python.
