Mantel-Haenszel chi-square test for stratified 2 by 2 tables

Table data:


        +ve -ve



        +ve -ve


This utility provides a Mantel-Haenszel chi-squared test for stratified data.

Inputs are:

  • - two 2 x 2 tables of stratified data;
  • - confidence level required; and
  • - desired precision of answers.

Outputs include:

  • - Chi-square statistic and corresponding P-value and odds ratio (with confidence limits) for each table;
