More about: Krippendorff's Alpha
What it calculates
The “Krippendorff's Alpha” calculator computes Krippendorff's α from 2 parameters: d_o (observed disagreement), d_e (expected disagreement).
A core calculation for studying, engineering tasks, and checking solutions.
Example calculation
With parameters D_o (observed disagreement) = 0.1, D_e (expected disagreement) = 0.5 the result is 0.8 (α = 1 − D_o/D_e).
