Description
Expand a counted seed subsample by mass.
Plant observations and seed or growth summaries depend on sampling area, observation time, material basis and inclusion policy. A local count or ratio can be consistent with the supplied records without estimating a complete population, establishing germination quality or identifying a growth mechanism.
Expand a counted seed subsample by mass.
When to use this tool
Use Seed Count Subsampling Weight when checking the stated botanical observation, seed, growth or coverage convention.
How to use the tool and how it works
- Enter countedSeeds, sampleMass, totalMass. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read expansionWeight, expandedSeedEquivalent. Use the output convention below.
Expand a counted seed subsample by mass. Require nonnegative whole countedSeeds, sampleMass > 0 and totalMass >= sampleMass; expansionWeight = total/sample, expandedSeedEquivalent = count*weight.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| countedSeeds | Counted Seeds | Required. Safe integer; minimum 0. |
| sampleMass | Sample Mass | Required. Finite number; strictly above 0. |
| totalMass | Total Mass | Required. Finite number. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| expansionWeight | Expansion Weight | Required. Finite number. |
| expandedSeedEquivalent | Subsample-based expansion assuming uniform density; it can be fractional. | Required. Finite number. |

}Limitations and assumptions
- This assumes a representative uniform seed-per-mass subsample; the output can be fractional and is not an observed whole-lot count.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.
Alternative or Complementary methods
Use verified observations and an appropriate sampling, growth or material-balance model; assess uncertainty and biological meaning separately.
