hello everyone i am here to find out more about my calculator. i have
been playing and teaching myself with 885 pages printed out into to
very big binders it is still hard to understand and follow the manual.
i can use algebraic mode pretty comfortably.
the problem is statistics. of everything that i have read rpn mode
seems to be the best mode because equation writer is still usable,
thank god for that option.
as far as the problem, storing the list seems to be quite hard. then
getting the statistics options to work properly is also quite hard.
there must be some shortcuts or easier way to operate this computer.
if anyone is able to help me i would be greatly appreciative for the
help.
john
p.s.
may be some clips on youtube.com would help promote this beautiful
piece of machinery as well

Switch to RPN! If you are one of those people who prefer ALG mode over
RPN, then with all honesty, a TI-89 will serve you better than a 50g
(and vice versa).

The data goes in a column of the [SIGMA]DAT matrix. For single
variable analysis, press RS 5[STAT] ENTER. There will be a field for
[SIGMA]DAT, and pressing F1 [EDIT] will open the matrix writer and
create the [SIGMA]DAT variable if it does not already exist. Then,
Col: lets you choose which column of [SIGMA]DAT to analyze. You can
then choose to let the calculator output any or all of Mean, Std Dev,
Var, Tot, Max, and Min.

Read the Statistics chapter of the manual (Chapter 18).
