# LOGNORM.DIST Function

The LOGNORM.DIST function is one of the statistical functions. It is used to return the lognormal distribution of x, where ln(x) is normally distributed with parameters mean and standard-dev.

The LOGNORM.DIST function syntax is:

LOGNORM.DIST(x, mean, standard-dev, cumulative)

where

x is the value at which the function should be calculated. A numeric value greater than 0.

mean is the mean of ln(x), a numeric value.

standard-dev is the standard deviation of ln(x), a numeric value greater than 0.

cumulative is a logical value (TRUE or FALSE) that determines the function form. If it is TRUE, the function returns the cumulative distribution function. If it is FALSE, the function returns the probability density function.

The numeric values can be entered manually or included into the cells you make reference to.
