Hi dear friend,
I am providing it with an example.
- I am sorry that the instructions from the maker of the calculator on
how to calculate a standard deviation fell short of your expectations.
All you have to do is follow them key stroke for key stoke, but enter
your own data. If a number is repeated 3 times like the number 55, you
can enter it 3 times or use the shortcut in the exemple
55 [2nd][FREQ]3 [Sigma+].
If
you make a mistake and enter the wrong number, use the [Sigma-] key to
remove it. That is similar to what a cashier does when an item is
entered twice: it is entered a third time but with minus sign.
Every
time an item is entered, the display shows the total number of items so
far. When it is finished the cashier press the key that sums up the
prices to get the total. This is the role of the [2nd][Sigma X] key
combination.
The average number of the data is obtained by the
[2nd][x bar] combination. The last two key combinations display the two
type of deviations.
I hope this will help you. Please vote for me.
Thanks in advance.
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.
