How do I obtain Fisher's exact test and chi-square for a two-way table in EXCEL?
A web calculator for 2x2 tables is [http://www.graphpad.com/quickcalcs/contingency1.cfm here.]
An EXCEL macro written by Russell John is available for [http://www.maths.murdoch.edu.au/units/statsnotes/inference/excelprocs2.html free download] but a slight modification needs to be made to work on CBSU machines.
In particular the Round () function is not recognized so an amended [attachment:fishchi.xls version] is available. This does not run on the CBSU wiki so save this EXCEL file to your PC and run from there.
The table of frequencies in any two-way table are placed in the EXCEL file and the macro run using tools>macro>macros. Choose TwoWayTable Macro and Run. This is also described, with a diagram, on the Russell's website (link above).
Please note the Monte-Carlo chi-square option in the EXCEL macro does not work on CBSU machines.
A MS-DOS program (fet.exe) which works on all Windows operating systems is available from [http://www.tulane.edu/~dunlap/psylib.html fo download or on-line use from here.]
