Q: I need to enter "1990-1991" on the graphing calculator for L1 to create a scatter plot. But idk how to enter the dash button? I know its not the negative or the subtract sign.
A: You can't. All lists, L1 to L6 included, can only hold quantitative numbers, and not strings. As a year, 1990-1991 would be a string, and not a number that holds much meaning.
If you have several of these (1990-1991, 1991-1992, etc), you're
I would actually advise against getting a TI at all. For stats you will not be using any of the graphing functions. The only advantage is that you will be able to do things like nCr etc which will come in handy.. but there are other much cheaper calsulators that also do those operations. I have a Ti-31 that does those operations and it only cost me about 15$! If you are not planning on going any deeper into mathematics or serious physics don’t waste your money.
Oh yeah, I should mention that I am a fourth year engineer and have made it through numerous stats and calculus courses without ever getting a graphing calculator. They are just not worth it.
Cheers
