One set of APA rules, applied everywhere
These formatters share the same APA 7 numeric and typography rules. Values bounded by 1 — such as p, r, standardized β, and effect-size coefficients — drop the leading zero. Statistics that can exceed 1 retain it. Exact p values use three decimals, while values below .001 appear as p < .001, never p = .000.
Where an exact sampling distribution is available, the tool recomputes p from the statistic and degrees of freedom and flags a mismatch worth double-checking, without assuming the entered result is wrong. Rounding, one-tailed hypotheses, and multiplicity corrections can all produce legitimate differences — the same reasoning behind the statcheck R package, which found reporting inconsistencies in roughly half of published psychology articles by running exactly this check at scale.
