k Drawing a Normal Probability Distribution Graph

You can draw a normal probability distribution graph using manual graphing with the Run-Matrixmode.

1. From the Main Menu, enter the Run-Matrixmode.

2. Input the commands to draw a rectangular coordinate graph.

3. Input the probability value.

Example

To draw a normal probability P (0.5) graph.

kCalculations Using the Distribution Function

You can use special functions in the Run-Matrixmode or Program mode to perform calculations that are the same as the Statistics mode distribution function calculation (page 6-49).

Example

To calculate normal probability distribution in the Run-Matrix mode for

 

the data {1, 2, 3}, when the population standard deviation is σ = 1.5 and

 

the population mean is  = 2.

1. From the Main Menu, enter the Run-Matrixmode.

2. Press the keys as follows.

!m(SET UP)2(Line)J

K5(STAT)3(DIST)1(NORM)

1(Npd)!*( { )b,c,d

!/( } ),b.f,c)w
