So, you can 'cluster' feedback under broad categories (for a single strategy - then, analysis can then be done using Multidimensional scaling (MDS) and Linear regression, to identify the most important categories on which immediate attention is needed, if resource allocation is a constraint .. I would assume that if you follow UCD, you would already establish marginal and ideal values for specific metrics associated with the product, something of that nature can also be incorporated for usability issues .. cause MDS is 'hectic').
if you are collecting preference ratings for 2 or more different strategies, you can do a t-test (this would differ on what kind of test you incorporate, depending on within or between subjects design) to see which is the more preferred strategy (indicated through statistical significance). again in your response you do mention WHAT you are doing, and I am trying to tell you HOW you might do things, I am not sure WHAT you are MEASURING, to be able to provide more input on the ANALYSIS side. hope this helps. sincerely kunal On Wed, 14 Nov 2007 21:20:42, Oliver Green <[EMAIL PROTECTED]> wrote: > > Good catch.
