# Students' Subject Preferences

A small survey-style dataset recording which school subjects five students like and dislike.
Each row is one student: their ID, the subjects they named as favorites, and the subjects they
named as least favorites. Subject names are in Mongolian Cyrillic.

## Files

| File | Rows | Description |
| --- | --- | --- |
| `data/train.jsonl` | 5 | One JSON object per student |

## Schema

| Column | Type | Description |
| --- | --- | --- |
| `student_id` | `int` | Student identifier, 1–5 |
| `favorite_subjects` | `list[string]` | Subjects the student likes (up to 3, in the order given) |
| `least_favorite_subjects` | `list[string]` | Subjects the student dislikes (up to 3, in the order given) |

## Example row

```json
{
  "student_id": 2,
  "favorite_subjects": ["Тамир", "Эрүүл мэнд", "Нийгэм"],
  "least_favorite_subjects": ["Монгол хэл", "Математик", "Уран зохиол"]
}
```

## Loading

```python
from datasets import load_dataset

ds = load_dataset("sumya123/students-subject-preferences")
print(ds["train"][0])
```

## Notes on collection and normalisation

* The raw responses were written in Latin-script Mongolian; subject names here are normalised to
  standard Mongolian Cyrillic spellings. The mapping applied was:
  `Angli hel` → `Англи хэл`, `niigem` → `Нийгэм`, `mat` → `Математик`, `pizik` → `Физик`,
  `gazarzui` → `Газарзүй`, `tamir` → `Тамир`, `Eruul mend` → `Эрүүл мэнд`,
  `Mongol hel` → `Монгол хэл`, `uran zoihol` → `Уран зохиол`, `tvvh` → `Түүх`,
  `himi` → `Хими`, `biologi` → `Биологи`, `undesni bichig` → `Үндэсний бичиг`,
  `hogjim` → `Хөгжим`, `oros hel` → `Орос хэл`.
* `ibo` is kept verbatim: the respondent confirmed it is a subject name but did not give its
  canonical spelling, so it was **not** guessed.
* Every student named exactly 3 favorites and 3 least favorites in the source list; the order
  within each list is the order in which they were reported and is not a ranking.

## Intended use

Reference data for school-subject preference questions, and a starting point for a larger survey
collecting the same fields. With 5 rows it is illustrative, not statistically meaningful —
no model should be trained or evaluated on it as if it were a real sample.
