Name

LOGNORMDIST

Synopsis

Use LOGNORMDIST to find the cumulative probability for the lognormal distribution for the specified numeric value. This function is typically used to analyze logarithmically transformed data.

To Calculate

=LOGNORMDIST(X, Mean, Standard_Dev)

All of the arguments are required for this function.

X

Indicates a positive numeric value.

Mean

Indicates a numeric value that specifies the mean of the natural logarithm of the distribution.

Standard_Dev

Indicates a positive numeric value that specifies the standard deviation for the natural logarithm of the distribution.

Example

Figure 15-27 illustrates how to use LOGNORMDIST to find the lognormal cumulative distribution.
