| Sintesi≠ | 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. | Krippendorff's alpha is a chance-corrected coefficient that quantifies the reliability of coding decisions made by two or more observers, and is the standard reliability statistic in communication content analysis. Unlike percent agreement, it corrects for the agreement expected by chance; unlike Cohen's kappa, it generalizes seamlessly to any number of coders, any measurement level (nominal, ordinal, interval, ratio), and data sets with missing values. |
