    "content": "The rendered table above summarizes all four numeric measurements (150 rows each, no missing values). Key takeaways from the query result:\n\n- **SepalLengthCm**: ranges 4.3 to 7.9 (range 3.6), mean 5.843, median 5.8, std dev 0.828, IQR 1.3. Mean and median are nearly equal, which suggests a roughly symmetric distribution.\n- **SepalWidthCm**: ranges 2.0 to 4.4 (range 2.4), mean 3.054, median 3.0, std dev 0.434, IQR 0.5. This is the tightest spread of the four and is also roughly symmetric.\n- **PetalLengthCm**: ranges 1.0 to 6.9 (range 5.9), mean 3.759, median 4.35, std dev 1.764, IQR 3.5. This has the widest spread, and the mean sits well below the median. That skew points to a non-unimodal distribution, with a cluster of very short petals alongside longer ones.\n- **PetalWidthCm**: ranges 0.1 to 2.5 (range 2.4), mean 1.199, median 1.3, std dev 0.763, IQR 1.5. The spread is large relative to its mean, and the mean is again below the median, like petal length.\n\n**Interpretation:** Sepal measurements are compact and roughly symmetric. Petal measurements are much more spread out and have a mean/median gap, so they are likely a mix of distinct subgroups. With three species in the data, the petal columns are the most likely to separate them. I did not break the columns down by species in this step, so that explanation is a hypothesis rather than a verified result."
