What is deviation standard


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!

How to calculate standard deviation


Hi there,


My name is adieh. Hav a great day.


Here are the tips on how to calculate standard deviation using a graphic calculator:



1. Turn on your graphing calculator, go to the stats/editor screen and enter your data set into list1. Once this is done, return to your home page by hitting the home button.

2. Push the catalog button and scroll through the applications until you find "stdDev(". Place the arrow next to it and press enter.

3.Type the word "list1" into the open parenthesis. After you have put that in, close the parenthesis so you calculator doesn't show an error message.

4. Press the enter button. The calculator has done the calculations and you now have the standard deviation of your data set.

Note:
Using 1-var stats in the stats/editor screen will also give you the standard deviation. Using that function will also give you other information associated with your data set.

Hope it helps.


Thank you for using fixya.

How do I put my calculator in statistics mode?


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):
  • [2nd] [CSR] - erase statistics data
  • [mib8888_17.gif] - add a number to the sample set
  • [2nd] [mib8888_18.gif] - remove a number from the sample set
  • [2nd] [FRQ] - multiple entry of the same sample value
  • [2nd] [n] - sample set size
  • [2nd] [mib8888_19.gif] - sum of all sample elements
  • [2nd] [mib8888_20.gif] - sum of the squares of all sample elements
  • [2nd] [mib8888_21.gif] - average of the sample set
  • [2nd] [mib8888_22.gif] - standard deviation (sample set is a complete set)
  • [2nd] [mib8888_23.gif] - standard deviation (sample set is a subset of a larger set)
The calculator displays "STAT" if the current sample set is non-empty.

Example: calculate the average and standard deviation of the set { 3, 4, 5, 5, 5, 5, 6 }.
  1. [2nd] [CSR] - erase stat memory
  2. 3 [mib8888_17.gif] 4 [mib8888_17.gif] 5 [2nd] [FRQ] 4 [mib8888_17.gif] 6 [mib8888_17.gif] - enter the data, note the use of [2nd] [FRQ] to enter the four occurrences of "5". Entering 5 [mib8888_17.gif] four times would have done the same.
  3. [2nd] [mib8888_21.gif] - display the average of the set, (4.714...)
  4. [2nd] [mib8888_22.gif] - display the standard deviation of the set (0.8806...)

Find the standard deviation of the following data set 5,5,5,5


The standard deviation is a measure on the variability of a number set from its average. Since all numbers in your set are the same, there is no variation from its average, and the standard deviation is 0.

How do I use the standard deviation function?


  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.

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.

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.
  1. Press STAT
  2. Select EDIT
  3. 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)
  4. 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!)
  5. Press STAT
  6. Select CALC
  7. Select OneVa
  8. Select LIST, NAMES, xStat(F2), Press ENTER
  9. The calculator provides Max, Min, Mean, Standard Deviation, Sum, Sigma, etc. You will be primarily interested in the Mean and Standard Deviation (sx).
