I took statistics last semester and I don't really remember how, but after you enter your data, you press SHIFT, then STAT (on the 1 key), then I think it's under 5 (VAR), and maybe Xon-1? Eh, funny how long you remember this stuff for....

I am happy that you found my solution helpful and even flattered that you copied it in this thread. By doing this, you gave me the opportunity to discover an error in my post. In fact, the calculator does provide a column for the frequency. If you enter nothing in the frequency column, all data items will have their frequency set to 1, by default.
Back to the current subject: How to get the variance (the square of the standard deviation).
When you finish entering your data:
While the symbol xSigma_n or xSigma_n-1 is still displayed with the blinking cursor to its right, press the [x^2] key above the [HYP] key. The screen displays say xSigma_n ^2. Press [=] to calculate the variance.
As my motto says, I am always happy to help, but happier still when people show true appreciation.
Hope it helps.

I am not sure how you can create such function (the range limitation do not work for x=c) but you can draw a vertical segment, just do not call it a function.
Draw a graph Y1=0
Then press SKETCH function key and use the F6 key to cycle through the TABS at the bottom of the screen. Look for the TAB named PEN. and click the function key below it.
Use the arrows to move the cursor to a spot on the screen (near the bottom), Press EXE to fix the starting point of the segment. Then use the Up arrow to draw a vertical segment from bottom to top.
