Here goes if you still need this...

STAT, EDIT, put information into L1 if only one variable stats, but put info into L1 and L2 if it is frequency table stats.

Then choose Stat, over to CALC, 1, enter...if 1 variable stats then press enter again. If frequency table stats, then choose STAT, over to CALC, 1, 2nd, 1 [L!], 2nd, 2 [L2], enter.

### 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.

1. Calculator must be in SD mode (standard deviation mode) :Press [MODE] [.]
2. However, if [FIX] or [SCI] appears on display you must press [MODE][9] first.
3. Data input always starts with [SHIFT][SAC], to clear the registers of old data.
4. Type a number and press the [DATA] key, it is the [M+] key at the bottom right of keypad.
After you finish entering the data

Press [SHIFT] [9] (sigma n-1) to get sample standard deviation
Press [SHIFT][8] (sigma n] for the population standard deviation
Press [SHIFT] [7] (xbar) for the mean
Press [SHIFT] [6] (n) for the number of data entries
Press [SHIFT] [5] (capital sigma x) for the sum of values
Press [SHIFT] [4] (capital sigma x to y) for the sum of squares of the values

For additional information you might consider taking a look at the calculator manual.

### 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.

### Standard Deviation

Press 2ND [CSR] to clear the stat data.

For each data point, enter the number followed by SIGMA+

If you have grouped data, enter the number followed by 2ND [FRQ] followed by the frequency then SIGMA+

Press 2ND [sigma x n] for the population standard deviation or 2ND [sigma x n-1] for the sample standard deviation.
