## TI 84

A darling.

If you go to STAT: EDIT: EDIT and enter a series of values into whichever of the lists

Then go to STAT: CALC: 1 (1-Var Statistics)

and indicate the list you want (2nd, 1-6)

You’ll get their average, their sum, the square of the sum, the standard deviation, the min, the max, and the quartile values.

Of course, you can do all sorts of nifty other statistics-related operations using this calculator, including a wide variety of t-tests and z-tests, statistical plotting, least square regression, etc. But we won’t go into those.

## If you really want to hear about it, the first thing you’ll probably want to know is where I was born, and what my lousy childhood was like, and how my parents were occupied and all before they had me, and all that David Copperfield kind of crap, but I don’t feel like going into it, if you want to know the truth. In the first place, that stuff bores me, and in the second place, my parents would have about two hemorrhages apiece if I told anything pretty personal about them. They’re quite touchy about anything like that, especially my father. They’re nice and all - I’m not saying that - but they’re also touchy as hell. Besides, I’m not going to tell you my whole goddam autobiography or anything.
