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 in older versions of EXCEL (pre-2010) or clicking the developer tab>Macros in EXCEL 2010. Choose TwoWayTable Macro and Run. This is also described, with a diagram, on the Russell's website (link above). The developer tab is not in the ribbon by default but can be added by clicking the File tab, clicking Options, and then clicking the Customize Ribbon category. In the Main Tabs list, select the Developer check box, and then click OK.
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 [http://www.tulane.edu/~dunlap/psylib.html for download or on-line use from here.]
