More about: Cohen's kappa
What it calculates
The “Cohen's kappa” calculator computes Cohen's κ from 2 parameters: p₀ (observed agreement), p_e (expected random).
A core calculation for studying, engineering tasks, and checking solutions.
Example calculation
With parameters p₀ (observed agreement) = 0.85, p_e (expected random) = 0.5 the result is 0.7 (κ = (p₀ − p_e) / (1 − p_e)).
