Counted males and females with both loss flags equal to zero, which means both the crusher and the scissor claw were present. Looked for a second claw width so the pre-registered 5 percent comparison could be computed. The table has CrusherClawWidth and no scissor-claw width, so no individual was scored as equal or unequal. https://w3id.org/delphi/resource/assessment/aristotle-ha04-05--claim-test http://www.w3.org/1999/02/22-rdf-syntax-ns#type https://w3id.org/delphi/ontology/Assessment https://w3id.org/delphi/resource/assessment/aristotle-ha04-05--claim-test http://www.w3.org/2000/01/rdf-schema#comment Measured: 0 individuals whose two claw widths were both present in the table (n = 2560). Interpretation: The quote is: There is no apparent difference between the male and female, for they both have one claw, whichever it may be, larger than the other, and neither male nor female is ever found with both claws of the same size. Lobster is read as Homarus, the clawed lobster, not every decapod. The claim is about both sexes and about the absence of equal claws. Which side is larger is not part of the claim. The denominator is the measured lobsters, not every lobster. https://w3id.org/delphi/resource/assessment/aristotle-ha04-05--claim-test http://www.w3.org/2000/01/rdf-schema#label Claim test of aristotle-ha04-05: inconclusive, confidence 0.88 https://w3id.org/delphi/resource/assessment/aristotle-ha04-05--claim-test http://www.w3.org/2000/01/rdf-schema#seeAlso https://github.com/fractastical/delphisci/blob/bf2af6ee0a84e23ffa6414ad7a0a50a8c276506e/test-data/claim-tests/aristotle-biology/aristotle-ha04-05/result.json https://w3id.org/delphi/resource/assessment/aristotle-ha04-05--claim-test http://www.w3.org/ns/prov#wasAttributedTo https://w3id.org/delphi/resource/agent/delphisci-claim-tester-grok-4-7 https://w3id.org/delphi/resource/assessment/aristotle-ha04-05--claim-test https://w3id.org/delphi/ontology/admissibleDatasets A public table of Homarus individuals with sex and a measurement or a crusher-versus-cutter code for both claws.

Mixed if both sexes are scored and exactly one of them is at or above 95 percent unequal while the other is from 50 percent up to but not including 95 percent. A sex below 20 measured individuals is not scored. If neither sex is scored, the verdict is inconclusive with reason data-unavailable when no claw-length table was fetched, and underpowered when a table exists but the floor is missed. https://w3id.org/delphi/resource/assessment/aristotle-ha04-05--claim-test https://w3id.org/delphi/ontology/hasConfidence 0.88 https://w3id.org/delphi/resource/assessment/aristotle-ha04-05--claim-test https://w3id.org/delphi/ontology/hasEvidence https://w3id.org/delphi/resource/evidence/aristotle-ha04-05--claim-test--dataset-1 https://w3id.org/delphi/resource/assessment/aristotle-ha04-05--claim-test https://w3id.org/delphi/ontology/hasVerdict inconclusive https://w3id.org/delphi/resource/assessment/aristotle-ha04-05--claim-test https://w3id.org/delphi/ontology/hypothesis In the lobster, both males and females have one claw larger than the other, and lobsters with two claws of the same size are absent. https://w3id.org/delphi/resource/assessment/aristotle-ha04-05--claim-test https://w3id.org/delphi/ontology/inferenceMethod Proportion unequal in each sex, floor 20, support threshold 0.95, refute threshold 0.50. https://w3id.org/delphi/resource/assessment/aristotle-ha04-05--claim-test https://w3id.org/delphi/ontology/passCriterion Supports only if both sexes are scored and, in each sex, at least 95 percent of individuals have unequal claws.
