STATISTICS HELP WITH TI 89 CALCULATOR

Can someone please help me figure out how to do one-var stats with 2 lists of data on the ti 89?? I’m doing discrete random variable in my statistics class and I need to find the mean and standard deviation of two lists of data.

Anyone??

If you google, “calculating mean and standard deviation with TI89,” what do you find?

I only find information on how to do one var stats with one list of data, not two.

I have a ti-89 also and I find it very troublesome so I am just borrowing a ti-84 from my school

I’m much too lazy to try to figure this out for you, but I remember doing it and I believe it had to do with assigning one of the lists to the frequency category.
