7. Distribution functions
The calculator has distribution features to find statistical calculations.
To enter the distribution menu,
1. Press S F (F DISTRI).
2. There are 15 options in the
3. Press E to select the function.
4. Input the specified values.
5. Press E to solve.
Note:
All functions of the distribution feature can be displayed as a graph
by using the graphing feature.
01 pdfnorm(
pdfnorm(value [, mean, standard deviation])
Finds the probability density of the specified value x for the normal
distribution N(µ, s
* When mean (µ) and standard deviation (s) are omitted, µ = 0 and
s = 1 are applied.
Example
Find the nominal distribution
probability density for x = 65
when the normal distribution of
the test score averages is 60
with a standard deviation of 6.
02 cdfnorm(
cdfnorm(lower limit, upper limit [, mean, standard deviation])
Calculates the normal distribution probability of a specified range x
for the normal distribution N(µ, s
* When mean (µ) and standard
deviation (s) are omitted, µ = 0
and s = 1 are applied.
Example
Calculate the probability of range
x = 54 to 66 in the above sample.
