• Normal Cumulative Distribution

5(DIST)1(NORM)2(Ncd)

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

Graph when an x-value is specified

Graphing is supported only when a variable is specified and a single x-value is entered as data.

• Inverse Normal Cumulative Distribution

5(DIST)1(NORM)3(InvN)

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

Area: probability value

(0 < Area < 1)

Inverse cumulative normal distribution calculates a value that represents the location within a normal distribution for a specific cumulative probability.
