I'd appreciate help in understanding the following. I have an unassuming little pair of independent proportions to test for significance. The Fisher exact test seems ideal.
I use a handy on-line calculator for the Fisher at: http://faculty.vassar.edu/lowry/fisher.html My proportions are 12/18 and 15/24; I need a 2-tail test. The results come back not significant, no surprise. But the exact p for these results or for one more extreme [the statistic generated by the Fisher] comes out as p = 1.0 That bugs me. How can such a thing be? And what does it mean? -Stephen ------------------------------------------------------------------------ Stephen Black, Ph.D. tel: (819) 822-9600 ext 2470 Department of Psychology fax: (819) 822-9661 Bishop's University e-mail: [EMAIL PROTECTED] Lennoxville, QC J1M 1Z7 Canada Department web page at http://www.ubishops.ca/ccc/div/soc/psy Check out TIPS listserv for teachers of psychology at: http://www.frostburg.edu/dept/psyc/southerly/tips/ ------------------------------------------------------------------------ --- You are currently subscribed to tips as: [EMAIL PROTECTED] To unsubscribe send a blank email to [EMAIL PROTECTED]
