Sunflowers Dominate in Size; Altitude Shapes Species Habitat

This analysis compares five plant species across eight measurements—from petal length to chlorophyll levels—revealing that sunflowers have the largest…

The Sunflower species stands out as the top performer in both measurements. It has the largest average petal length at 12.01 cm and the largest average stem thickness at 14.00 mm. A grouped bar chart has been generated showing the average petal length and stem thickness for all species side by side, making it easy to compare across the dataset.

All seven measurements show a positive relationship with petal density pct, except native altitude which has a slight negative association. Petal width is the strongest predictor, followed by stem thickness and petal length. Two charts were generated: a bar chart showing all correlations and a scatter plot of the top relationship.

The analysis produced two visualizations and supporting data tables comparing average sepal, petal, and stem measurements across the five species. A grouped bar chart shows side-by-side comparisons of all five measurements per species, making it easy to spot which species are larger or smaller overall. A heatmap provides an at-a-glance color-coded view of how each species ranks across every measurement type.

A line chart was generated showing how mean chlorophyll index varies across native altitude ranges (below 0m to 300m+) for each of the 5 species. Overall, altitude has very little effect on chlorophyll levels, with a near-zero correlation of -0.092.

The analysis reveals how the sepal-to-petal length ratio differs across the three Iris species. Two charts were generated: a box plot showing the full distribution of ratios per species, and a bar chart comparing the mean ratios with standard deviation error bars. Setosa stands out with the highest ratio, meaning its sepals are much longer relative to its petals. Virginica has the lowest ratio, indicating its petals are relatively longer compared to its sepals. Versicolor falls in between.

Native altitude varies meaningfully across all five species, revealing clear habitat preferences. Two visualizations were generated — a box plot showing altitude spread per species and an overlaid histogram showing distribution shapes — along with a detailed summary table. Orchids occupy the highest elevations (mean ~747m), followed by Iris Versicolor (~651m), Rose (~547m), Iris Setosa (~498m), and Sunflowers at the lowest (~401m). The overall altitude range spans from -563m to 1,954m across all species.

The analysis produced summary statistics and bin distribution tables for petal density pct and chlorophyll index across all species. Five data tables were generated showing the computed metrics and density segment breakdowns (Low: <40%, Medium: 40–65%, High: 65%) for each species.

The Pearson correlation matrix for all 8 morphometric traits has been computed and visualized as an interactive heatmap with annotated coefficients. The heatmap uses a red-blue color scale to clearly distinguish positive (blue) and negative (red) correlations at a glance.

The IQR-based outlier detection was performed on petal width cm and sepal width cm across your 200,000-row dataset. Two box plots were generated — one for each column — with outlier points highlighted in crimson red, making them easy to identify visually. The plots clearly show the distribution of each measurement and flag any values that fall outside the 1.5x IQR fences.

The analysis of stem thickness across the dataset reveals a right-skewed distribution with a mean of 6.757mm and a median of 5.460mm. The gap between mean and median confirms the rightward skew (1.399), meaning a portion of observations have notably thicker stems pulling the average up. The standard deviation is 4.301mm, indicating considerable spread. The excess kurtosis of 1.357 signals heavier tails than a normal distribution — more extreme values than you'd typically expect. Two visualizations were generated: a histogram with a KDE overlay showing the overall shape of the distribution, and side-by-side box plots breaking down stem thickness by species, making it easy to compare medians, spreads, and outliers across groups.
