"How much ABX sessions do you perform ? What were the results ? Generally, I've stopped when pval was low enough. FOr some files, I've ruined the results by doing some mistake. Angry, I've damaged even more the results. Therefore, for some files, I've went up to 50 trials in order to reach again satisfying pval." Note: pval, in ABX testing, is the probability that the results of the experiment are due to random guesses. -- Ron Olsen ------------------------------------------------------------------------ Ron Olsen's Profile: http://forums.slimdevices.com/member.php?userid=9233 View this thread: http://forums.slimdevices.com/showthread.php?t=32352 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/audiophiles
