How to generate an NORM.INV FUNCTION formula using AI.

To obtain information on the ARRAY_CONSTRAIN formula, you could ask the AI chatbot the following question: “To get the NORM.INV formula from an AI chatbot, you could ask the following question: "What is the Excel formula to calculate the inverse of the cumulative normal distribution (NORM.INV)?"

NORM.INV FUNCTION formula syntax

The NORM.INV function in Excel is used to calculate the inverse of the normal cumulative distribution for a specified probability. The syntax for NORM.INV is as follows: NORM.INV(probability, mean, standard_dev) - probability: This is the probability value for which you want to find the corresponding value from the normal distribution. It must be between 0 and 1. - mean: This is the mean or average value of the distribution. - standard_dev: This is the standard deviation of the distribution. Note: The mean and standard deviation must be provided as arguments, and they should be numeric values. The NORM.INV function returns the value from the normal distribution that corresponds to the given probability.

Use Cases & Examples

In these use cases, we use the NORM.INV function to calculate the inverse of the cumulative distribution function for a specified probability in a normal distribution.

Calculate Z-score

Description

In this use case, we use the NORM.INV function to calculate the Z-score of a given value in a normal distribution. The Z-score represents the number of standard deviations a value is from the mean.

Result

NORM.INV(x, mean, standard_deviation)

Generate random values from a normal distribution

Description

In this use case, we use the NORM.INV function along with other functions to generate random values from a normal distribution. By providing different values for x, mean, and standard_deviation, we can generate a range of random values that follow a normal distribution.

Result

NORM.INV(RAND(), mean, standard_deviation)

Calculate confidence interval

Description

In this use case, we use the NORM.INV function to calculate the upper and lower bounds of a confidence interval for a given mean and standard deviation. The confidence interval represents the range within which we can be confident that the true population mean lies.

Result

NORM.INV(alpha/2, mean, standard_deviation)
