Normal Distribution
: Population standard deviation ( > 0)
: Population mean
Student-
t Distribution
df : Degrees of freedom (df > 0)

2
Distribution
df : Degrees of freedom (Positive integer)
F Distribution
n:df : Degrees of freedom of numerator
(Positive integer)
d:df : Degrees of freedom of denominator
(Positive integer)
u Common Parameters (x, Lower, Upper)
When the Tail setting is { } (X), { } (X), or { } (X=) ({ } (X=) is for
discrete distribution only)
x: Data value
When the Tail setting is {
} (X)
Lower: Lower boundary
Upper: Upper boundary
x, Lower, and Upper are used in calculations as described below, in accordance with the Tail
setting.
{
} (X≤): x or lower cumulative probability calculation
{
} (≤X≤): Lower or greater, Upper or less cumulative probability calculation
{
} (X≥): x or greater cumulative probability calculation
{
} (X=): Probability calculation for x (discrete distribution only)
Note
• The values you input for each parameter are retained for each distribution type, even if the
parameters of multiple distribution types share the same name. For example, the “p” for
binomial distribution and the “p” for geometric distribution are both retained as separate
values. The values of “x”, “Lower”, and “Upper” are also retained individually for each
distribution type.
