I loaded 3,276 water samples, dropped every row with a missing value and plotted how many were safe to drink. The notebook stops there.
Original tutorial by Aman Kharwal: Water Quality Analysis (opens in a new tab)

|---|---|---|
| Water samples | 3,276 | |
| Missing pH values | 491 | |
| Missing sulfate values | 781 |
Cell # counts every cell from the top of the notebook, Markdown included, starting at 1.
No model was trained.
