Alpha Agreement

Since mathematical assertions of Alpha`s statistical distribution are always approximations, it is best to get alpha distribution by bootstrapping. [12] [13] The distribution of Alpha leads to two clues: the sum on the same nc, nk and n only ock. Regarding these coincidences, Krippendorffs Alpha: here, α interval > α nominal “display style” “alpha” “α > alpha” “α” When the frequencies observed ov ≠ v. on average proportional to the expected frequencies ev ≠ v`, α interval – α nominal “alpha” “display style” “The above corresponds to the usual form of the α “display style” once it has been algebraically simplified. [10] Values range from 0 to 1, with 0 total disagreement and 1 a perfect match. Krippendorff proposes: “[I] usually demand α ≥ .800. While preliminary findings are still acceptable, α ≥.667 is the lowest possible limit (2004, p. 241). Krippendorffs Alpha generalizes several known statistics, often called inter-coder agreement indicators, inter-referenced reliability, reliability of coding of certain unit sets (unlike unitzing), but it also differs from statistics called reliability coefficients, but which are not adapted to the specifics of the coding data generated for subsequent analyses.

Comparing alpha coefficients on different metrics can provide insights into how coders design the metric of a variable. It is often used in content analysis to quantify the extent of seat matching, and differs from most other measures of reliability among advisors, as it calculates differences of opinion (contrary to an agreement). This is one of the reasons why statistics are probably more reliable, but some researchers report that, in practice, the results of Alpha and Kappa are similar (Dooley). When it describes a statistic as a statistic of consistency, reproducibility or reliability, it does not become a valid clue as to whether coded data can be relied upon to make future decisions.
