Length (source-scaled) against Rings (count); 300 source observations — 300 evenly spaced row positions including first and last; deterministic, not a random or representative sample. Source: UCI Abalone, CC BY 4.0. X: supplied source-scaled length. Y: ring count. No rescaling or age conversion is performed.

What the columns mean

The source contains a sex/category field, seven continuous physical measurements and ring count. UCI documents prior removal of missing records and scaling of continuous values by division by 200. We preserve the supplied numeric values and label length as source-scaled rather than presenting it as an untransformed millimetre measurement.

What this chart helps you inspect

The chart selects source rows floor(i × 4176 / 299) + 1 for i from 0 to 299. This includes the first and last rows and spaces selected positions across the file. It is deterministic and reproducible, but it is not random sampling and carries no representativeness guarantee. The manifest lists every selected one-based row number.

Limits of this resource

The complete CSV exceeds this editor’s 2,000-observation limit. Use the 300-row file for this chart or analyze the complete data in another environment. Ring count remains ring count; this chart does not relabel it as exact age. The subset cannot establish population relationships, and the source’s earlier preprocessing is separate from our conversion.

Calculated from the plotted rows

Variable	N	Minimum	Maximum	Mean
length	300	0.13	0.78	0.5323666666666664
rings	300	3	27	10.136666666666667

These descriptive values are computed from the chart CSV at build time. They summarize the plotted selection only and are not population estimates. No rows are removed during chart preparation beyond the explicit selection rule above.
