Question about Sharp EL-738 Scientific Calculator

How do i get a standard deviation? How do i get the Mean? Where can i find the manual that will explain to me the statistical procedures on this calculator? (i actually have a Staples model BD-6703, but it wasn't available in your choices)

Hi,

a 6ya expert can help you resolve that issue over the phone in a minute or two.

Best thing about this new service is that you are never placed on hold and get to talk to real repairmen in the US.

the service is completely free and covers almost anything you can think of.(from cars to computers, handyman, and even drones)

click here to download the app (for users in the US for now) and get all the help you need.

Goodluck!

SOURCE: standard deviation

Enter the first number, 1.

Hit the σ+ (Sigma+) key. ( n=1 will appear in the window)

Enter the second number, 1.

Hit the σ+ (Sigma+) key. (n=2 will appear in the window)

. . . . .

Enter the last number, 7.

Hit the σ+ (Sigma+) key. (n=7 will appear in the window)

Hit 2nd x2 (by hitting the 2nd key you are actually selecting the x-bar written above the key.) This gives you the mean.

Hit 2nd sqrt(x). This gives you the sample standard deviation which we will use in class.

Make sure you turn your calculator off and on for new data sets.

SOURCE: Standard Deviation

When I enter some series of data and check the descriptive statistics, every time I come to the standard deviation the calculator shows me Error 1 message.

Is there a PDF with the Statistical procedures for this product? I bought my Casio FX-115 used (second hand). No instructions. I need help using the Statistical functions for my Stats classes:

Correlation Coefficient

Standard Deviation/Variance

Chi-Square

x-x(bar) summations

HELP!

SOURCE: Trying to find standard deviation on the calculator

I took statistics last semester and I don't really remember how, but after you enter your data, you press SHIFT, then STAT (on the 1 key), then I think it's under 5 (VAR), and maybe Xon-1? Eh, funny how long you remember this stuff for....

Hello,

You must first enter the data you are doing statistics on.

After you finish entering the data, do as the figure below describes.

Hope it helps.

Mean absolute deviation.

Let's break it down into its components.

Mean - Average

Absolute - absolute value - sign doesn't matter - if negative, make positive

Deviation - difference from the mean

Let's do an example. Population 3 7 4 2. Total 16. Mean (Average) 16/4 = 4.

Deviations

3 - 4 = -1 absolute value 1

7 - 4 = 3

4 - 4 = 0

2 - 4 = -2 absolute value 2

Sum of these deviations 1 + 3 + 0 + 2 = 6

Mean (average) of these deviations is 6 / 4 = 1.5.

Good luck,

Paul

The standard deviation is a measure of how "tight" the samples are distributed around your mean.

In layman's terms, a small standard deviation indicates that most of your measurements are in the vicinity of the means; a large standard deviation corresponds to readings that are all over the place.

You could also say that the smaller the SD, the more your mean is representative of the data set.

For a better explanation, just look up Standard deviation on Wikipedia!

Full instructions are in the "Statistical Calculation" section beginning on page E-44 of the manual. If you need a manual, you may download a copy here.

In short, you go into the STAT mode, bring up the STAT Editor screen, enter the 50 data points, then calculate the mean and standard deviation.

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

There isn't one. Press the "STAT VAR" button to bring up the statistics menu. "Sx" and "Sy" will give you the sample standard deviations, while "sigma x" and "sigma y" will give you the population standard deviations.

When I say "sigma" I mean the lower case Greek letter sigma, which looks like a lower-case "o" with a tail pointing to the right.

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 30XA doesn't have a statistical mode; all of the statistical functions are available at all times.

2nd [CSR] clears the statistical registers, Sigma+ adds a data point, Sigma- deletes a data point, 2nd [x-bar] gives the mean, 2nd [sigma-x-n] and 2nd [sigma-x-n-minus-one] give the population and sample standard deviation.

For full details, refer to the statistics section in the manual. If you don't have a manual, you can download a guidebook from

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.
