Based on the dataset's characteristics, **Petal Length (`PetalLengthCm`)** stands out as a highly discriminative and important numeric metric, as it is traditionally the strongest feature for distinguishing between the different Iris species (particularly isolating *Iris-setosa* from the others). Here are the records representing the extreme ends of this metric: * **Highest Petal Length (6.9 cm):** * **Species:** Iris-virginica (Record ID: 119) * **Other Measurements:** Petal Width: 2.3 cm | Sepal Length: 7.7 cm | Sepal Width: 2.6 cm * **Lowest Petal Length (1.0 cm):** * **Species:** Iris-setosa (Record ID: 23) * **Other Measurements:** Petal Width: 0.2 cm | Sepal Length: 4.6 cm | Sepal Width: 3.6 cm These extremes perfectly highlight the morphological differences between the species, with the *virginica* specimen showing a petal length nearly seven times larger than the *setosa* specimen.
