Since you already know if your answers are right or wrong, you must have decided in advance the total number of trials. How much are you going to do
Nothing has been decided. I need some experience with the protocol in order to have more confidence I've found the right one. One choice to consider in the future is the choice of music. In the two trials today, I used very different kinds of music---exciting brass music in trial one, and chamber/vocal music in trial two. While this did not affect my ability to distinguish the cables, it did affect which one I preferred. I am considering that the chamber/vocal music may be superior for future tests, because "getting it right" requires a certain delicacy and resolution. In contrast, the brass music was quite exciting no matter what cable was used.
And I have to be realistic---I don't know how many trials I can ultimately do. Moonboy has the summer off, so we have a few months to try to get something accomplished---but I work full-time and dont' want to do more than a couple trials per day, at least until I'm more sure how my critical faculties function under these conditions.
I already checked my answers because, given the trouble this is, I want to make sure I'm not wasting my time before going too far down this road.
So my first hope is to do enough trials to convince myself
that I'm hearing something. For example, if I get 5/6 correct and feel pretty confident I knew what I was hearing, that will be good news for me.
After that, then the hope would be to do enough trials to get a statistically significant result, at least 20.
