k Poisson Distribution
u Poisson Probability
Poisson probability calculates a probability at a specifi ed value for the discrete Poisson
distribution with the specifi ed mean.
( x = 0, 1, 2, ···)
μ : mean ( μ > 0)
Perform the following key operations from the statistical data list.
5(DIST)
6(g)1(POISN)
1(Ppd)
The following shows the meaning of each item when data is specifi ed using list specifi cation.
Data ............................ data type
List .............................. list whose contents you want to use as specifi ed data
(List 1 to 26)
μ ................................. mean ( μ > 0)
Save Res .................... list for storage of calculation results (None or List 1 to 26)
Execute ....................... executes a calculation
The following shows the meaning of a parameter data specifi cation item that is different from
list data specifi cation.
x ................................. ( x > 0)
After setting all the parameters, use c to move the highlighting to “Execute” and then press
the function key shown below to perform the calculation.
• 1(CALC) ... Performs the calculation.
