|FOR STATS HP-67 RULES!|

I love to stir up discussion. But for standard deviation anyway this seems to be the case and perhaps in other ways too. I must also say that it was through this forum that the "gummy" wheel got fixed.

For stats the 49 (+ or not) rules, afew tests have been added from the 48 and you can install STAT49PRO that adds all the basic tests you would ever need unless you are a real statistician.
Of course input method through matrices might be a bit more cumbersome, but it is easy to update and the matrix writter is fast. And there is no gummy wheel, just the keyboard.
