| सारांश≠ | Scott's pi is a chance-corrected coefficient of intercoder agreement for two coders working on a nominal scale, introduced by William Scott in 1955 specifically for content analysis. It improves on raw percent agreement by subtracting the agreement two coders would reach by chance, where chance is estimated from a single pooled distribution of categories shared by both coders rather than from each coder's separate marginals. | Holsti's method is a percent-agreement reliability index for content analysis, popularized by Ole Holsti's 1969 textbook and derived from Osgood's earlier formula. For two coders it is twice the number of coding decisions on which they agree divided by the total number of decisions each made — a simple, intuitive measure of how often coders reach the same judgment. |
