How to run this notebook (Google Colab)

1. Open the notebook in Google Colab.
2. Upload both dataset files into the session's /content folder (the default working directory):
   • In the left sidebar, click the Files icon (folder), then the Upload button, and select:
     • pone_0206767_s002.xlsx (Zendle et al., 2019 — player survey data)
     • game_coding_50games.xlsx (original game coding dataset)
   • Note: uploaded files are stored in session storage only and are deleted when the runtime disconnects, so they must be re-uploaded each session.
3. Install dependencies by running this in a cell: !pip install pandas scipy matplotlib seaborn openpyxl
4. Run all cells top to bottom (Runtime → Restart and run all).
