SOURCE: ti 84 is giving me the wrong answer. it show e
Possibly beacuse the settings are different try changing it back so the settings on the mode that are on the left hand side except for the clock to be all highlighted.
SOURCE: My TI-84 Plus gives answer as 2.145274703E14, what Is E?
E is the calculators form of scientific notation. so 2.145274703E14
is really 2.145274703 x 10^14 or 214527470300000

Your calculator is set in radians. Press mode key. Arrow down to 3rd line. Highlight degree and press enter. Your calculator is now in degrees, not radians. To get out of the mode screen and back to home screen, press 2nd and then mode.
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.
