Your calculator does not have graphing capabilities. It cannot draw distributions or any type of graphic.

Well you need to know the shape.

The [U n/d] key allows users to input mixed fractions using the TI-30XS/B or TI-34 MultiView scientific calculator. For example, to input 2 3?4, follow the instructions below:
• Input 2 and press [2nd] [U n/d].
• Input 3 and press [down].
• Input 4 and press [right] [enter].

Example: Enter the following x variables, and determine the sample and population standard deviations.
x = {1,2,3}

• Press [DATA] and begin to enter the data as indicated into the L1, L2 or L3 lists. To input a data point, type the value and press [ENTER]. Press the down arrow key to move on to the next data point.
• Press [2nd], [STAT], and then choose 1-VAR.
• For the "DATA" option, choose the listname the data is stored in (L1, L2 or L3). For the "FRQ" option, choose "ONE" since this data does not include a frequency list.
• Arrow down to "CALC" and press [ENTER].
  
  Answers should be as follows:
  3:Sx (Sample Standard Deviation) = 1
  4:sx (Population Standard Deviation) = 0.816497
• Press [2nd] [MODE] to exit STAT mode.

I have the exact same problem (just happended recently) with my TI-5045 II after 25 years of good service. My solution? I just bought another model: Sharp EL-1801V at Stapels for about $31.00. To get the old one fixed will probably cost me $25.00-30.00 just to diagnose, plus shipping and parts and labor. And that assumes I can find a shop to do it, or that TI still stocks the part(s) gone bad. Same old problem with all technology.

Refer to page no 13 of user manual of calculator. (TI-30XS / TI-30XB MultiView™ Guidebook - Texas Instruments - US and Canada) It will solve your problem.

Try the Ti site. I doubt it is still available as it is a very old machine.

Are the batteries fresh? Try putting new ones in. If that doesn't help then your LCD display is probably damaged and it will probably get worse. Can it be fixed...probably, but what's worth to you? If the calculator is only worth $50 (IDK?) but they want $100 to fix it at an electronics repair shop...is it worth it?
