Drawing A Normal Probability Distribution Graph; Calculations Using The Distribution Function - Casio FX-CG20 AU User Manual

k Drawing a Normal Probability Distribution Graph
You can draw a normal probability distribution graph using manual graphing with the
Run-Matrix mode.
1. From the Main Menu, enter the Run-Matrix mode.
2. Input the commands to draw a rectangular coordinate graph.
3. Input the probability value.
Example
1 m Run-Matrix
!m(SET UP)2(Line)J
2 !4(SKETCH) 1(Cls) w
5(GRAPH) 1(Y=)
3 K6( g) 3(PROB) 6( g) 1(P() a.f)w
k Calculations Using the Distribution Function
You can use special functions in the Run-Matrix mode or Program mode to perform
calculations that are the same as the Statistics mode distribution function calculation (page
6-50).
Example
1. From the Main Menu, enter the Run-Matrix mode.
2. Press the keys as follows.
• For details about what you can do with the distribution function and its syntax, see
"Performing Distribution Calculations in a Program" (page 8-41).
To draw a normal probability P (0.5) graph.
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
!m(SET UP)2(Line)J

1(Npd) !*( { ) b,c,d
!/( } ) ,b.f,c)w
