Technically, ABX gathers data points on whether the humans think they detect an audible difference. You then apply statistics to compare the results against random values. So you can say "we found X percent of the humans reported a difference, which with the sample size, lets us reject that its random with Y confidence. Usually Y has to be 95% or so before its considered science. There is always a chance, in this case 5% that there was no difference, or that the results were random. Doing ABX as opposed to AB testing just allows us to make the same statement with fewer data points. -- Pat Farrell http://www.pfarrell.com/ _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/audiophiles
