What it calculates
The “Fleiss' kappa” calculator computes Fleiss' κ from 2 parameters: p̄ (mean agreement), p̄_e (random).
A core calculation for studying, engineering tasks, and checking solutions.
Example calculation
With parameters P̄ (mean agreement) = 0.7, P̄_e (random) = 0.4 the result is 0.5 (κ = (P̄ − P̄_e) / (1 − P̄_e)).
