    "reasoning": "I have the gold table Iris_by_Species showing aggregated statistics by species. To identify the most important numeric metric, I need to consider which measurement best distinguishes between species (has the highest discriminative power). Looking at the ranges:\n\n- SepalLengthCm: ranges overlap significantly (setosa 4.3-5.8, versicolor 4.9-7.0, virginica 4.9-7.9)\n- SepalWidthCm: ranges overlap (setosa 2.3-4.4, versicolor 2.0-3.4, virginica 2.2-3.8)\n- PetalLengthCm: shows clear separation (setosa 1.0-1.9, versicolor 3.0-5.1, virginica 4.5-6.9) - NO overlap between setosa and others\n- PetalWidthCm: also shows good separation (setosa 0.1-0.6, versicolor 1.0-1.8, virginica 1.4-2.5)\n\nPetalLengthCm appears to be the most discriminative metric with the clearest separation between species. Now I need to find the actual individual records with the highest and lowest PetalLengthCm values from the raw data."
