Formula Generator - NORM.INV function
The NORM.INV function is used to calculate the inverse of the cumulative distribution function for a specified probability in a normal distribution. It returns the value that corresponds to the specified probability, mean, and standard deviation.How to generate an NORM.INV formula using AI.
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 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.
Calculate Z-score
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.
NORM.INV(x, mean, standard_deviation)
Generate random values from a normal distribution
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.
NORM.INV(RAND(), mean, standard_deviation)
Calculate confidence interval
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.
