SOURCE: how do you use the statistics function to find out

Press [2ndF][MODE][1] to select single variable statistics.

- Enter a value and press [DATA]
- or enter value, press [X,Y]key, enter the frequency then press [DATA

The xbar may be a key accessed directly if xbar symbol is on top of the key, or a [2ndF] key if xbar is written on the body of the calculator.

Find the formula for the correlation coefficient and use the calculator to calculate it.

You can also use the calculator to do statistics. It has some keys to retrieve the statistical values calculated. You will find r among them.

Please do read your manual to learn how to do statistics.

There must be an error in what you report. You pressed MODE then 4: Base-N and now your calculator is in base-N calculation mode (the DEC, Hex, BIN, OCT) numeration keys are active.

To do statistics you must put the calculator in STATS mode.

Press MODE: You have 6 computational modes to choose from

1: COMP, the general computational mode

2:CMPLX, for calculation s with complex numbers,

3: STAT for statistics,

4: Base-N, binary, octal, decimal, and hexadecimal numeration

5: Equation, solving mode, etc..

**For statistics, choose 3:STAT**

It depends what the two list mean.

If you are doing 1-var statistics you may want to enter the frequency of a data element (if some are repeated) in the list L2.

In that case when you run the CALC 1-Var , you first press the F6 key to set the lists Data List1, and Frequency List 2.

Once you set the lists, press the F1 key to select 1-var. The calculator will give all the statistics of the distribution.

If you are doing 2-var stats SET the lists and press F2 2-var. The calculator will give you the x-statistics, followed by the y-statistics.

The TI-30Xa does not have a statistics mode. That statistics operations are available at all times, just like addition and subtraction. Just enter the data with Sigma-plus and then calculate the desired statistics---mean, standard deviation, and so forth.

Full details are in the "One-Variable Statistics" section of the guidebook (page 9 in my copy). If you need the guidebook, you can download one from

This will show you how to do statistics (calculate average, standard deviation, regressions etc.) as to the mode and median refer to the definitions.

TO COMPUTE STANDARD DEVIATION AND 2-VAR STATISTICS.

I assume you know the theory. I will show you the key strokes

For 1-Var statistics

Press [MODE][3:STAT] [1:1-VAR]. You are ready to enter values in the X column.

Enter a number and press [=]. Cursor jumps to second number to enter.

Keep entering numbers and pressing [=] till all numbers are in. Press the [=] key after the last one.

**Press
[AC] key to clear the screen.**

Press [SHIFT] [STAT] (above digit 1.) then [5:Var]. Screen displays the statistical variables 1:n ;2: x bar; 3: x sigma n; 4:x sigma n-1.

Press the number corresponding to the statistical value you want, ex 1:n . The variable appears on screen. Press [=] and it will be displayed.

To display another variable press [SHIFT][STAT][5:Var][ 1,2, 3, or 4] .

To access the sum of squares sigma x^2 and the sum of data sigma x press[SHIFT][STAT][4:SUM] then [1: for sigma x^2] or [2: for sigma x]. Press [SHIFT][STAT][6:MinMax] to access minX and maxX.

For 2-var statistics

To perform 2 variable statistics you press [MODE][3:STAT] and any of the other regression options (except 1:1-Var). A two column template opens where you enter the X and Y values. When finished entering data, press [SHIFT][STAT][5:Var]. to access the different statistics. As I assumed above, you should be able to recognize what each variable means.

The TI-30XA does not have to be switched to a statistics mode, the operations are available all the time. The choice of operations are somewhat limited; the calculator offers statistics functions for one dimensional data sets only (no linear interpolation of (x,y) value pairs, for example):

Example: calculate the average and standard deviation of the set { 3, 4, 5, 5, 5, 5, 6 }.

- [2nd] [CSR] - erase statistics data
- [] - add a number to the sample set
- [2nd] [] - remove a number from the sample set
- [2nd] [FRQ] - multiple entry of the same sample value
- [2nd] [n] - sample set size
- [2nd] [] - sum of all sample elements
- [2nd] [] - sum of the squares of all sample elements
- [2nd] [] - average of the sample set
- [2nd] [] - standard deviation (sample set is a complete set)
- [2nd] [] - standard deviation (sample set is a subset of a larger set)

Example: calculate the average and standard deviation of the set { 3, 4, 5, 5, 5, 5, 6 }.

- [2nd] [CSR] - erase stat memory
- 3 [] 4 [] 5 [2nd] [FRQ] 4 [] 6 [] - enter the data, note the use of [2nd] [FRQ] to enter the four occurrences of "5". Entering 5 [] four times would have done the same.
- [2nd] [] - display the average of the set, (4.714...)
- [2nd] [] - display the standard deviation of the set (0.8806...)

I have no clear idea what you mean by solve statistics problem. But if your problems involve finding the standard deviation and other statistical values then this post will help you.

The variance is the square of the standard variation

Press 2nd [STAT] then select CLRDATA to clear statistics data. Select 1-VAR or 2-VAR for one-variable or two-variable statistics. Press DATA and enter your data (x for 1-VAR or x and y for 2-VAR). Press 2nd [EXIT-STAT] and select N. Press STAT-VAR to see a menu of statistics variables and their values. Sx (and Sy) will give you the standard deviation, sigma-x (and sigma-y) will give you the population standard deviation.
