**Common questions about the LOGNORM.INV formula include:**

- What is the LOGNORM.INV formula?

- What does the formula do?

- What does the syntax look like?

The LOGNORM.INV formula can be used to

**calculate a cumulative probability (also known as a “percentile”) based on an observed quantity from a lognormal distribution**. It can also be used to determine the lognormal probability density for a given value.

The LOGNORM.INV formula can be

**commonly mistyped**as LOGNORM.F or LOGNORM.NEV, as the letters "F" and "NEV" are very close to "INV".

**Some common ways the LOGNORM.INV formula is used inappropriately**is by using it to calculate probabilities associated with a normal (gaussian) distribution, or by forgetting to include the mean and standard deviation of the lognormal distribution, which are necessary in order to calculate the probability.

**Some common pitfalls**when using the LOGNORM.INV formula include mistyping the formula, failing to include the mean and standard deviation of the lognormal distribution in the formula, or having an incorrect value for the cumulative probability.

**Common mistakes**when using the LOGNORM.INV Formula include not including the mean and standard deviation of the lognormal distribution in the formula, as well as using an incorrect value for the cumulative probability.

**Common misconceptions**people might have with the LOGNORM.INV Formula include thinking that it can be used to calculate probabilities associated with a normal (gaussian) distribution, and thinking that it only requires a single value for the probability, when in fact it requires both the mean and standard deviation of the lognormal distribution as well.
