    "content": "The only meaningful categorical column is **Species**, and it is perfectly balanced. Each of the three values appears 50 times, or 33.3% of the 150 rows:\n\n- Iris-setosa: 50 (33.3%)\n- Iris-versicolor: 50 (33.3%)\n- Iris-virginica: 50 (33.3%)\n\nBecause the three classes tie, there is no single \"most common\" species. That balance means accuracy is a fair metric for a classifier, and stratified sampling is straightforward.\n\nThe other text columns are ingestion metadata, not analytical categories. Each has one value repeated in all 150 rows (100%):\n\n- `_batch_id`: batch_ac5a1636e093\n- `_source_file`: /home/nettle/.cache/kagglehub/datasets/uciml/iris/versions/2/Iris.csv\n- `_source_system`: api\n\nThese carry no information for separating the species. The frequency table above comes from the query result already rendered."
