title: Extension of Fisher's exact test to 2-by-k contingency tables: a computer program in BASIC.
abstract: A randomisation method of analysis for 2 X k contingency table data has been developed. This method, which is based on the fundamental principle of Fisher's exact probability test, gives a more accurate evaluation of the significance probability than does the chi-square test, especially when the sample size is small. A listing from the computer program in BASIC to carry out the 'exact probability test' for analysis of 2 X k contingency table data is available from the authors.
