Hi
standard devition is easy once you get your head around it for grouped data you have to take the equation apart so put in the sum of f then bracket (x-mean) squared and then divide by the sum of f and square root everything on the calculator. And then for non-grouped data you need to do the sum of (x-mean)squared then divided by the sum of n and once again square root everything.
Hope this helps
Good Luck

### Where is s on the ti-30xa calculator

If you mean the standard deviation, there are two shifted keys on the third row marked with a lower-case Greek sigma. sigma_xn is the population standard deviation and sigma_xn-1 is the sample standard deviation.

### SC-6103 aurex prestige calculator

You must have pressed the MODE key followed by SOLV , QUAD or SIMUL-2 or SIMUL-3 . If the calculator has these a programs they solve a Quadratic equation, a simultaneous system of two linear equations (SIMUL-2) . a system of 3 linear equations (SIMUL-3).

To use these solvers (IF YOU ARE INTERESTED), you select the solver you want and you will be prompted for a first coefficient (a, or a1). You enter the value and press the DATA key and you will be prompted for the next coefficient.

To exit the Solver mode press the MODE key followed by the key next to which there is DEC or >DEC. It might also be marked COMP.
Sorry, I do not have that very calculator but an other AUREX Scientific calculator (DS-752C).

### Does this calculator comes with a standard deviation or population standard deviation button

Yes. The sample standard deviation is 2nd [sigma x n-1] and the population standard deviation is 2nd [sigma x n].

### Cant get it into degree mode for oct mode

If you want to use degrees (to have a DEG appear on top of the screen) you must exit all base-N modes (bin, oct, hex, or pent if available) and set the calculator numeration mode to DEC, decimal (the usual computational moode). The other modes are appropriate for handling certain types of calculations with integer (whole) numbers.

### Is there a formula for standard deviation problems

Hello,
Of course there are formulas for those calculations. You find them in books on statistics. Do not worry, the calculator has been programmed to use them. All you have to do is learn how to get the calculator to give you the results.

If you still want to see the formulas with your very eyes, I suggest you go to the local library, ask a math teacher, an accountant, or launch a Google search for them.
Hope it helps.
