THE RESULT
What the data shows
The largest computed metric is 0.784 for F; the smallest is 0.76 for I. Metric: median_diameter_ratio (Diameter / length).
The source category I denotes infant specimens, not a third adult sex. Ratios use the source scaling consistently.
| sex | specimens | median diameter ratio | median height ratio | median rings |
|---|---|---|---|---|
| F | 1,307 | 0.784 | 0.2692 | 10 |
| I | 1,342 | 0.76 | 0.25 | 8 |
| M | 1,528 | 0.7818 | 0.2679 | 10 |
THE METHOD
From source to answer
Positive-length ratios and category-level robust summaries.
The Python source exposes this study’s transformations. The complete project download includes shared preparation and evaluation routines.
THE NEXT DECISION
What follows from the finding
Investigate biological sampling composition before pooling specimen categories in a measurement study.
Where the conclusion stops
Physical measurements use source scaling. Rings are the modeled target; the source describes an approximate age conversion. Site and animal group identifiers are unavailable, limiting biological generalization.
Related studies may reuse observations or holdouts. These are historical analyses; associations and backtests do not demonstrate commercial impact. Further model tuning needs new, untouched evaluation data.
