Hey guys. I've been procrastinating a little bit, and with the test tomorrow, I'm having to write out the whole equation (which takes about 10 minutes and is about 3 miles long). I need to know how to plug it into my TI-83 so I can actually do all of the problems on my test tomorrow. I know how to get to the standard deviation. I get to:
2nd - Stat, then scroll to MATH, and then go down to StdDev(
I don't know what to plug into the parenthasies from StdDEV(
If any of you can help, it'd greatly be appreciated.
I'd like to elect a president that has a Higher IQ than a retarted ant.

Here's the way my professor taught us to do it. Remember the acronym..
The first letter of each word is the next step that needs to be done.
1.)Mean - figure out the mean (average) of all the numbers being used
2.)Dogs - figure out the deviation of all the numbers being used
3.)Send - square each of the deviations
4.)Meannies - figure out the mean of all the new numbers from step three.
5.)Running- then get the square root of the answer to step four.
After step five you should have the standard deviation.
I know you wanted to know how to put in into the TI-83, but since I can't help you there hopfully this can make it easier if you end up doing it on paper
Right rudder....Right rudder...Come on, more right rudder....Right rudder......Aw forget it, I quit!!
