Youcan use the procedures belowto perform sevendifferent t ypesof
distribution calculations.
1. Press @!i!)<i>IID(DIST)to enter the DIST Mode.
2. On the menu that appears, select a distribution calculation type.
3. Input values for the variables.
.
With Binomial PO, Binomial CD, Poisson PO, and Poisson CD, you can
input sample data and then perfonn calculations.
4. After inputting values for all of the variables, press 151.
.
This displays the calculation results.
.
Pressing
151
or @ while a calculation result is displayed will retum to
the input screen of the first variable
Note:
.
To change the distribution calculation type after you enter the DIST
Mode, press I!i!!Im(STAT/DIST)m(Type) and then select the distribution
type you want.
.
Distribution calculation accuracy is up to five significant
dig~s.

List Screen
(Binomial PD, Binomial CD, Poisson PD,
Poisson CD)
With Binomial PO, Binomial CD, Poisson PO, and Poisson CD, use the List
Screen forsample data input.Youcan inputup to 25 data samples for
each
variable. Calculation results are also
displayed
on the List Screen.
