Question about Texas Instruments TI-86 Calculator

I accidentally dropped my calculator onto the floor and the LCD inner screen cracked. Is there any replacement for it?

There is a faint metal coating on the glass where the cable attaches, you would have to find another screen with the same spacing, of the horizontal and vertical lines, and try to attach the horizontal and vertical cables to that.

The difficulty of finding a replacement LCD maybe would cost more than having a new one. and even if can find a replacement, installing it would again be very difficult! circuit to LCD connector is fixed, once remove, there'll be no guarantee that it would still function normally! try to disassemble your calculator and see if you can manage to disconnect and reconnect the LCD itself!

The median is the number is the middle.

Using the calculator, you can follow the Statistical Calculations (Stat) on pages 22 and 23 of the attached manual. http://support.casio.com/pdf/004/fx-570_991ES_PLUS_E.pdf

However, it might be quicker to just put the numbers is order from lowest to highest and pick out the number in the middle.

For example, take the numbers 3, 5, 4, 7, 6, 4, 9.

Putting them in order, we get 3, 4, 4, 5, 6, 7, 9

There are 7 numbers so we want the 4th number (3 numbers to the right and 3 numbers to the left). In this case, the 4th number is 5 and that is our median, as half the numbers are lower than it and half the numbers are higher than it. It the number of numbers is even, you take the average of the two middle numbers.

Good luck,

Paul

What do you mean by "reg mode"? The calculator modes and how to change them are listed beginning on page E-5 of the manual: http://support.casio.com/pdf/004/fx-570_991ES_PLUS_E.pdf

Get the Plus. It adds a few functions, takes nothing away, and is the same price at most vendors.
