Press the MODE key repeatedly until you see "Fix Sci Norm" on the top line. You can then choose a display mode.

If you don't want any digits after the decimal point, select Fix and then 0. Alternatively, you can select one of the "Norm" modes, which will show you nonzero digits to the right of the decimal point.

Can you please help me on how to calculate mean, median, mode, standard deviation calculation on casio fx-991ms scientific calculator


This will show you how to do statistics (calculate average, standard deviation, regressions etc.) as to the mode and median refer to the definitions.

TO COMPUTE STANDARD DEVIATION AND 2-VAR STATISTICS.

I assume you know the theory. I will show you the key strokes

For 1-Var statistics
Press [MODE][3:STAT] [1:1-VAR]. You are ready to enter values in the X column.
Enter a number and press [=]. Cursor jumps to second number to enter.
Keep entering numbers and pressing [=] till all numbers are in. Press the [=] key after the last one.
Press [AC] key to clear the screen.
Press [SHIFT] [STAT] (above digit 1.) then [5:Var]. Screen displays the statistical variables 1:n ;2: x bar; 3: x sigma n; 4:x sigma n-1.
Press the number corresponding to the statistical value you want, ex 1:n . The variable appears on screen. Press [=] and it will be displayed.
To display another variable press [SHIFT][STAT][5:Var][ 1,2, 3, or 4] .

To access the sum of squares sigma x^2 and the sum of data sigma x press[SHIFT][STAT][4:SUM] then [1: for sigma x^2] or [2: for sigma x]. Press [SHIFT][STAT][6:MinMax] to access minX and maxX.

For 2-var statistics
To perform 2 variable statistics you press [MODE][3:STAT] and any of the other regression options (except 1:1-Var). A two column template opens where you enter the X and Y values. When finished entering data, press [SHIFT][STAT][5:Var]. to access the different statistics. As I assumed above, you should be able to recognize what each variable means.

You can configure it as you wish. Press [SHIFT][MODE] to access the (SETUP) configuration screen, then select [8:Norm].

You will be prompted to choose Norm1 or Norm2. To help you find out which is more appropriate to meet your concerns, I am inserting a screen capture from the manual.

Different answer two different calculators ti-81 and ti89


I had the same problem when I got my first 89, even though it's really a feature and not a problem.

Press the diamond key then enter to get your answer, and it will give you the decimal answer instead of the exact answer like you have been getting. Hope this helps...

Different answer fro my TI-89 AND MY tI-81


Hello,
Your TI81 can only perform numerical calculation: It always give uour numbers. The TI89, a more sophisticated calculator, can of course do numerical calculation, BUT ALSO symbolic ones. You ask it for the derivative of sin(x) and it will give you cos(x).
Anyway, if you want a decimal result for you calculation above one of the numbers must have a decimal point (instead of writing 2PI write 2.PI.

The TI 89 can do exact calculations. But if you want approximate results any number in the sequence of operations must have the mark of a decimal. Numbers without decimal marks are considered integers, Integer numbers with a decimal mark are treated as floating point numbers ( meaning decimal).

Hope it clarifies things for you.
