Chi-squared adjusted for ties

WebMay 5, 2024 · Something can be done about that discreteness of available significance levels, which is of practical help at least some of the time; one can use a second suitable test (and a third in its turn, if the second is also discrete) to break ties and so generate a finer set of available significance levels. In some cases that's quite valuable. http://www.biostathandbook.com/kruskalwallis.html

WebThe continuity-adjusted chi-square for tables is similar to the Pearson chi-square, but it is adjusted for the continuity of the chi-square distribution. The continuity-adjusted chi-square is most useful for small sample sizes.
