The theoretical basis for using N - 1 rather than N in a chi squared test of a 2 × 2 table or in a comparison of two proportions Since the chi squared test was first used as a statistical test of two-by-two tables, the standard procedure has been to compare the formula (see nomenclature) against the chi squared...

Two-by-two tables nomenclature One of the commonest problems in statistics is the analysis of a two-by-two table, i.e. a table of the form: _______________________________________________________ B not-B Total _______________________________________________________ A a b m not-A cd n Total r s N _______________________________________________________...

Should randomised trials be analysed differently to other comparative trials? Summary Several authors have concluded that a randomised trial is a special case of a comparative trial, and should be analysed differently (by the Fisher-Irwin test). There are counter-arguments to this, and the recommendation here...

Why do the charts of maximum Type I error have a sawtooth appearance Figure 1 of main paper This sawtooth appearance is particularly evident for comparative trials analysed by the K Pearson chi squared and N - 1' chi squared tests (Figure 1 of the main paper, reproduced above). In summary, it can be described...

Two-by-two table calculator
Use this utility to analyse two-by-two tables by the 'N - 1' chi squared test. Enter the four counts in the four boxes and select 'Calculate'. Provided the minimum expected number is at least 1, you will be given the two-sided P value. Otherwise you will be advised to use the Fisher-Irwin test. This is valid for...
