I used all 100 samples for each.  A Z-Score is how many standard deviations a sample is from the mean.  It's a way of adjusting for Julia tending to use numbers in the range 7-9 while I was mostly using 4-6.  http://en.wikipedia.org/wiki/Standard_score", "timestamp": "1337524785"}, {"author": "Mac", "source_link": "https://www.facebook.com/jefftk/posts/367810046609510?comment_id=368067676583747", "anchor": "fb-368067676583747", "service": "fb", "text": "Thanks for the stats lesson.  On the band's progress, to my ear, you have gotten better in musicianship -- you play your instruments better.  It would be hard not to after that many years.  But craft is only part of a performance.  You guys have always had high energy, which is more important to the dancers.  Hence, perhaps, the perception that you have not changed all that much since starting.  Tangent:  A musician once told me that contra music is repetitive and gets boring.  Thus, when bands go off and produce a CD, they play stuff that entertains themselves.  This seems borne out by the fact that the CD you buy at the end of the evening is frequently not the music you just heard -- sometimes not even the same type.  If live music can be recorded with adequate quality, simply recording gigs and selecting tracks over a year, would produce a great CD for the dancers.  One of my favorite CDs is \"Rainy Night in Montague\", which has live tracks.  You can hear the dancers balance, which makes great percussion and is hugely meaningful to the dancers.  From your live library, could you come up with a CD's worth of tunes?  I'd buy it.  Yeah, dances are usually longer than CD tracks.  You'd have to edit.  \"Free Raisins - Live!\"", "timestamp": "1337527304"}, {"author": "Jeff Kaufman", "source_link": "https://www.facebook.com/jefftk/posts/367810046609510?comment_id=368218789901969", "anchor": "fb-368218789901969", "service": "fb", "text": "@Walker: I've thought about trying to cull a CDs worth of music, but the level of quality people expect from a CD is very high.  If we wanted to make it into a CD we'd need to be capturing recordings with each instrument as a separate track.  Most dances can only give me one or two tracks (with whatever on them we want).  Audrey's board can do what we want, but unless we're running sound for ourselves we'd be asking other people to use her board, which I doubt most people would be up for.", "timestamp": "1337545580"}, {"author": "Kiran", "source_link": "https://www.facebook.com/jefftk/posts/367810046609510?comment_id=368223333234848", "anchor": "fb-368223333234848", "service": "fb", "text": "Audrey's board is simple enough that a decent sound person could run it.
