median

[Chris Pem10]

I'm not aware of any other computer program, language, or calculator that defaults to the lower element. I just tested Mathematica, Matlab, R and Excel and they all return the average of the two central elements. In 10 minutes of googling I couldn't find one example where the author didn't just average the two central elements... I'm not saying you're wrong per se; but this will probably bork many things; silently and without error. Like spreadsheets.
