**Common questions about NORM.INV formula:**

-What is a normal inverse (NORM.INV) function?

-What parameters are needed to use this function?

-What does the NORM.INV function do?

**How to use NORM.INV formula appropriately:**

The NORM.INV formula can be used to calculate a number that is associated with a normal probability distribution given the probability, mean and standard deviation values. The formula uses the syntax, NORM.INV(probability, mean, standard_deviation)

**How to commonly mistype the NORM.INV formula:**

The most common error when using the NORM.INV Formula is mistyping the parameters; that is, mixing up the order of probability, mean, and standard deviation values.

**Common ways the NORM.INV formula is misused:**

-Using the NORM.INV formula for values that are not associated with a normal probability distribution

-Using the NORM.INV formula to calculate probability instead of the inverse calculation

-Using the NORM.INV formula to calculate a non-normal probability distribution function

**Common pitfalls when using the NORM.INV Formula:**

-Using incorrect parameters

-Not double-checking the values that are input in the formula

-Failing to account for the accuracy of the calculation

-Using the same parameters repeatedly over time

**Common mistakes when using the NORM.INV Formula:**

-Using the wrong probability value or mean and standard deviation values

-Forgetting to use the NORM.INV formula to make a reverse calculation to verify accuracy

-Miscalculating the probability, mean, or standard deviation values

-Using a NORM.INV formula to calculate a non-normal distribution function

**Common misconceptions people might have with the NORM.INV Formula:**

-Believing that the NORM.INV formula can only be used to calculate normal distributions

-Assuming that the NORM.INV formula can only calculate one probability at a time

-Thinking that NORM.INV is the only formula used to calculate probabilities associated with normal distributions
