Okay, wait, I'm gonna printscreen it from the textbook, cause I think it has instructions for t-nspire too.

And this is generally about Lists http://scr.hu/0hj9/h9btw

It's Hease and Harris instruction from textbook, you should be able to google it if you want it all.

Awh, but that's a CASIO Guide, isnt it Oo? Because mine does not look like that

And I Found out how to do it now!

For everybody with a TExas instrument having the same issue as me

Do the same as everybody say

Stat:Edit

Stat->CALC-1 var statistics

Then, dont click enter, because before you click enter, you will need to decide the calculator to look ad L1 and L2.... So you fill in [2nd]L1,[2nd]L2

The "," sign is important! IF you do not fill it in there will be a Syntax Error!

Hope this will do it

I used this guide

pg. 32

Okay, yeah, that's what I thought when I posted the pdf-file earlier. I saw that step and thought it could be of significance. Stupid of me not pinpointing that out, though, because then you could have solved this much earlier!

Anyways, good job on figuring it out!
