Hello! Today I'm going to show you how to get 1 Variable Stats on to your TI-83.
To do that you need a list
And to access that, you're going to have to go to the STAT button right here
So you'll see this screen
And then from there, you can either press one
or Enter to access that
So you're going to see an empty list
So all you have to do is add numbers
So you just type it in like normal
and then press ENTER to go to the next value
If you need to, you can also go back and edit numbers or delete them from your list
And then to go back to the main screen,
all you got to do is press the 2ND key which is the yellow one and then MODE
And that is gonna allow you to go back to the main screen
Okay, so now we want to get the 1 Var Stats
And to do that, we need to go the column that says CALC
and it's real easy. Just press the right arrow key and that's going to take you there
Just pick the first one, 1-Var Stats and press ENTER
So now we just need to get that list
And there's two ways you can do it
The first way is just pressing 2ND and the number according to that list
So 2ND + 1 will give you the first list
The other way is to just press 2ND and then STAT to bring up all the lists that are there
And just select it
And once you do, you're gonna be able to calculate it by just pressing ENTER
And that's going to give you all the values here that you need
So I put a little legend on the right side to let us know exactly what each one is
And you're gonna be able to answer those STATS questions for your homework
In case you don't have a calculator, you can also use Statdisk Online
Now all you need to do is sign in with Google or you can sign up with an email to get quick and easy access
Now I already signed up so it's going to take me automatically here and you're going to see something like this
So I already put the same data as before
and it works like Excel
You have columns here, where you can enter your value(s)
Now keep in mind that you have to put all these values in one column
Otherwise, it won't take it in
And this info is easy to get
So just go to "Data" right there and then look for the one that says, "Explore Data, Descriptive Statistics"
Now we need to select the column that we put our data in and then once we do,
you just "Evaluate"
So once this information pops out, it's going to give you all the information you need for your homework
So here we have everything we need. Including the boxplot, the histogram, and a normal quantile plot
If you have any questions, please let me know in the comments
Thank you and have a great day! I hope this helps out.
