Calculation method
Calculation method
Tie-corrected Kruskal–Wallis H
Ranks pooled, H=12/(N(N+1))sum(Rj²/nj)-3(N+1), divided by tie correction.
Degrees of freedom
Ranks pooled, H=12/(N(N+1))sum(Rj²/nj)-3(N+1), divided by tie correction.
Asymptotic upper-tail p value
Ranks pooled, H=12/(N(N+1))sum(Rj²/nj)-3(N+1), divided by tie correction.
Symbols and units

- Independent groups JSON
Use the units shown. A list keeps the order in which you enter its values. The symbol ^ means “raised to the power of”.
Calculation steps and notation
sum(list) adds all entries in the list.
Assumptions & limits
Assumptions & limits
- Calculation uses the entered values and stated mathematical model; quantities must use the labelled units. Supported limits: All required fields must be finite values of the exact declared type and within displayed bounds. Lists contain1–1000 finite numbers. JSON tables are numeric rectangular rows, at most100 rows and30 columns; individual tools have stricter shape/domain constraints. Ranks pooled, H=12/(N(N+1))sum(Rj²/nj)-3(N+1), divided by tie correction.
