This video. Im gonna show you how to do standard deviation on your ti ti 30x calculator and the best way to do this as always is just go into a very simple and very quick example just got saved either here youll notice that the twelves are repeated. So im going to have to use a frequency function.
So that we dont have to type 12. Repeatedly so more efficient okay so the first thing we need to do is get our calculator into stat mode. Lets go.
Its already ins that would be ill show you again so second function and then stacked. Which is on this data. Key and we want one variable statistics.
Weve just got one set of data.

If we had like an x and a y series maybe we were doing some sort of regression. You would need two variable so just press equal. So the second function stat equals that gets us into the stat mode.
So we can now enter data. So unsurprisingly you just press. The data key.
Ive already entered the data in here. So just go five press down twice seven down twice nine time twice then 10 to the 12. Were doing 12.
Ill show you that again 12.

Its over five years. So it grating frequencies by last step very simple we just do the calculation this calculator does in a very nice way as youll see if we press the stat via button. Here just press that calculates everything for you so weve got n of nine.
You cant b.s there is of course nine of them press their long key. We get to x bar.
X.

Bar. Is our mean so that gives us the mean of the data. Moving along one more time.
Weve got this three point three. Two this is what the calculator calls s x. This is your standard deviation based on the n.
Minus. One definition. So youre taking your standard deviation and on the bottom of the fraction youve got n minus.
One move along one more time.

Youve got this three point one three this is a standard deviation when youre just dividing by n. Instead of n minus one so thats how you do standard deviation as one final point. You probably dont be stuck in this mode.
Forever. So. If you press second function.
And then the stat there so youve got exit stat and then enter for yes. That gets you out of the stat mode. So your calculator is now back to normal.
If you already statistics you have to go back into the statistics mode. So hopefully. This has been helpful to you and thank you very much for watch.
