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 there,

Save hours of searching online or wasting money on unnecessary repairs by talking to a 6YA Expert who can help you resolve this 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.

Here's a link to this great service

Good luck!

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!

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

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.

Jill. She scored two standard deviations above the mean, while he only scored one-and-a-half standard deviations above the mean.

Texas Instruments TI-86 Statistics How-To Information
The following instructions should allow you to calculate the mean and standard deviation using a TI-86 calculator.

- Press STAT
- Select EDIT
- Enter data into a list: [2.32 ENTER 2.43 ENTER 2.39 ENTER, etc.] Continue until all data have been entered. (use arrows keys to go to the y value, if any)
- EXIT until you reach the main ("blank") screen. (If you try to calculate while you're in the data menu, it thinks you're still trying to enter data!)
- Press STAT
- Select CALC
- Select OneVa
- Select LIST, NAMES, xStat(F2), Press ENTER
- The calculator provides Max, Min, Mean, Standard Deviation, Sum, Sigma, etc. You will be primarily interested in the Mean and Standard Deviation (sx).

This calc will do standard deviations. In the manual it is on page 2 and also on page 40.
