When two (or more) observers independently classify objects or observations into the same set of mutually exclusive and exhaustive k categories, it may be worthwhile to use a measure that summarizes the extent to which observers conform in their classifications. The Kappa coefficient, first proposed by Cohen (1960), is such a measure. . . .

In addition, you leave the proportion of objects assigned to Observer Category i and the percentage of objects assigned to The J category of Observer 2.

If these proportions or sampling probabilities are represented in a two-sided contingency table with k-lines and k columns, pij becomes the probability in the cell corresponding to line i and column j. With the i line, which is like column i 1, …, k, the diagonal of this table presents probabilities pii (i 1, …, k) the… Access to the content of society newspapers varies according to titles.
