Formula Generator - NORMINV function
The NORMINV function returns the value of the inverse normal distribution function for a specified value, mean, and standard deviation. It is commonly used in statistical analysis to calculate Z-scores, generate random values that follow a normal distribution, and estimate percentiles in a normal distribution.How to generate an NORMINV formula using AI.
To obtain the NORMINV formula for a specific dataset without prior knowledge of the function, you could ask the AI chatbot the following question: "What is the Excel formula to calculate the inverse of a normal distribution given a specific probability and dataset?"
NORMINV formula syntax.
The NORMINV function in Excel is used to calculate the inverse of the normal cumulative distribution for a specified probability. Here is a clear and concise overview of the NORMINV syntax: NORMINV(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 arithmetic mean or average of the distribution. - standard_dev: This is the standard deviation of the distribution. The NORMINV function returns the value from the normal distribution that corresponds to the given probability, mean, and standard deviation.
Calculating Z-scores
In this use case, we use the NORMINV function to calculate the Z-score for a given value, mean, and standard deviation.
NORMINV(x, mean, standard_deviation)
Generating random values
In this use case, we use the NORMINV function to generate random values that follow a normal distribution with a specified mean and standard deviation.
NORMINV(RAND(), mean, standard_deviation)
Estimating percentiles
In this use case, we use the NORMINV function to estimate the value at a given percentile in a normal distribution with a specified mean and standard deviation.
