Subject: Statistical evaluation of categorical data From: Piotr Majdak <piotr.majdak(at)OEAW.AC.AT> Date: Tue, 3 May 2005 16:22:21 +0200Dear list, I've got some categorical data (Yes/No responses) from ONE subject as responses to acoustical stimuli under different conditions. Each condition was repeated 60 times, shuffled with all conditions in one experiment - just the method of constant stimuli. Four independent variables control the conditions, 2-3 categories each one (some of them are ordinal). Now I'd like to analyse the main effects and interactions of all variables on the responses. Do you know how to treat the data and which evaluation method am I supposed to use? Can you point me to some references about evaluation of this kind of data? Thanks in advance, Piotr Majdak -- Please avoid sending me Word or PowerPoint attachments.
