It depends on how easy it is to tell them apart. If you can tell them apart 100% percent of the time, such that you did so on the first five tries, that would be statistically significant at the .05 level. If you could only tell one from the other 51% of the time, you'd have to do a lot more than 16 trials to get a statistically significant difference from random guessing (which would be 50%). -- Mike Anderson 'FREE RADICAL RADIO!'
