Normal Cumulative Distribution; Inverse Normal Cumulative Distribution - Casio FX-CG20 AU User Manual

• Normal Cumulative Distribution

Normal Cumulative Distribution calculates the normal
cumulative probability of a normal distribution between a
lower bound and an upper bound.
Calculation Result Output Examples
When a list is specified
• Graphing is supported only when a variable is specified and a single
data.

• Inverse Normal Cumulative Distribution

Inverse Normal Cumulative Distribution calculates the
boundary value(s) of a normal cumulative distribution
probability for specified values.
Inverse cumulative normal distribution calculates a value that represents the location within a
normal distribution for a specific cumulative probability.
