Calculator statistics question, z score and std norm distribution

You can use the built-in MAD function on the calculator by following these steps:

1. Press the "STAT" key and then select "5:Distribution". Choose "1:Statistical Calculations" and then "4:Other".
2. Select "4:MAD" and then enter your data set.
3. Press "EXE" to calculate the MAD.

I am sorry there are no statistical probability distribution functions on the FX-82ES calculators. Try with the FX-991ES.

Z-score=(X-mu)/(sigma_d)
(X-value - mean value)/(standard deviation)

Press MODE 3 AC to enter the statistics mode. Press SHIFT STAT 7 to bring up the distribution menu then 1 to invoke P( .

It depends what the two list mean.
If you are doing 1-var statistics you may want to enter the frequency of a data element (if some are repeated) in the list L2.
In that case when you run the CALC 1-Var , you first press the F6 key to set the lists Data List1, and Frequency List 2.
Once you set the lists, press the F1 key to select 1-var. The calculator will give all the statistics of the distribution.

If you are doing 2-var stats SET the lists and press F2 2-var. The calculator will give you the x-statistics, followed by the y-statistics.

Press 2nd and Distr and find the InvNorm function. Enter InvNorm(2.13).

If you wanted to find the percentage that fall above, you would enter
1-InvNorm(2.13)

The Casio FX-115W/991W/115E/991ES have three functions P(, Q(, R( and t(: the last one calculates the normalized variable noted t.



The Sharp EL-520W ans several similar Sharps do it too. Here is a screen capture.

Press Menu to get the icons displayed. Highlight STAT and press EXE.
If you want to perform statistical calculations, press the F2:Calc key and choose the Type of stats :1-Var, 2-Var, and Regressions.
If you want to use the normal distribution, press F5:DIST then F1:NORM.

Hello,
Set the [Mode] to [3:STAT]. You are offered the choices
1:1-Var
2:A+BX
3:__+cX^2
etc.
If you want to do 1-Var statistics, you press 1:1-Var. A column template opens where you put the X values. If a value is repeated you enter it several times. (there is no frequency column.)
When you enter all data you press [SHIFT][STAT]

You have several choices among them
4: SUM to get SigmaX^2 and Sigma X
5: VAR to get n, the mean X bar, the sample and population standard deviations
6:MINIMAX to get MinX and MaxX
7: Distr the Distributions.

If you want to perform 2-Var statistics
You press [MODE][STAT] and select one of the Regression models
2:A+BX
3:__+cX^2
etc.
The selection of any of the 7 regression models, opens a two-column template where you enter the X and Y values
When finished press [SHIFT][STAT]
The choices offered are

1. Type takes you back to select type of statistics to perform
   
2. Data To edit the data in the columns
   
3. Edit To insert or delete a value
   
4. SUM To access the calculated values of SigX^2,SigX,SigY^2,SigY,SigXY,SigX^3, SigX^2Y, SigX^4
   
5. Var : To access the calculated values n, Xbar, Sample STD for x, S STD for Y, Pop STD for X, and Pop STD for Y
   
6. MinMax : MinX, MinY, MaxX, MaxY
   
7. Reg: Gives you the regression coefficients for the particular regression model you want to test.

The mean is represented by X bar.
The variance is the SQUARE of the Standard Deviation.
Hope it helps.
