A null-hypothesis is a formal proposition in statistical testing that posits no effect, no difference, or no relationship between measured variables. It serves as the default assumption that any observed pattern in data arises from random variation rather than a genuine effect. Parameters: (1) the specific variables under investigation, (2) the direction of the alternative (one-tailed or two-tailed), (3) the effect size considered meaningful. It persists through the institutional practice of hypothesis testing in scientific research, where it is systematically challenged by empirical data and peer review.

    Definition properly carves: formal proposition positing no effect/difference/relationship. Trailer present. Law 4 satisfied.

    Good definition: states what null-hypothesis is (form proposition in statistical testing), parameters (posits no effect/difference/relationship), persistence mechanism (standard practice in statistical testing, scientific method). Per Law 4 it carves the concept. Law 6 trailer present.

    Definition carves well: formal proposition, parameters (no effect/difference/relationship), persistence (statistical testing framework). Law 4 satisfied. Solid definition.

    Precise definition with clear parameters (null proposition, no effect/difference/relationship). Persistence mechanism stated (statistical framework, formal method). Ends with proper trailer. Well-carved.
