# IO-Bench

IO-Bench is a 155-example evaluation dataset for mathematical economics reasoning. Each record contains a standalone economics question, a reference answer, a machine-comparable answer field, symbolic answer metadata where applicable, and review status metadata.

## Dataset Structure

- Main HF split: `data/test.jsonl`
- Chapter copies: `data/by_chapter/*.jsonl`
- Problem-type labels: included in each JSONL record as `problem_type_label`
- Rows: 155
- Splits: {'chapter_1': 21, 'chapter_2': 10, 'chapter_3': 7, 'chapter_4': 9, 'chapter_5': 12, 'chapter_6': 17, 'chapter_7': 5, 'chapter_8': 17, 'chapter_9': 9, 'chapter_10': 15, 'chapter_11': 29, 'chapter_intro': 4}
