Formula Generator - NORM.S.INV function
The NORM.S.INV function is used to calculate the inverse of the standard normal cumulative distribution for a given probability. It returns the value x such that NORM.S.DIST(x) = probability.How to generate an NORM.S.INV formula using AI.
To obtain the NORM.S.INV formula from an AI chatbot without prior knowledge of its existence, you could ask the following question: "What is the formula in Excel to calculate the inverse of the standard normal cumulative distribution?"
NORM.S.INV formula syntax.
The NORM.S.INV function in Excel is used to calculate the inverse of the standard normal cumulative distribution. It returns the z-score corresponding to a given probability. The syntax for NORM.S.INV is: NORM.S.INV(probability) - probability: This is a required argument that represents the probability for which you want to find the corresponding z-score. It must be a value between 0 and 1. Example usage: =NORM.S.INV(0.5) In this example, the function will return the z-score corresponding to a probability of 0.5, which is the median of the standard normal distribution.
Calculate Z-score
In this use case, we use the NORM.S.INV function to calculate the Z-score for a given value. The Z-score measures how many standard deviations an observation or data point is from the mean of a distribution.
NORM.S.INV(x)
Determine Confidence Interval
In this use case, we use the NORM.S.INV function to determine the critical value for a given confidence level in order to calculate the confidence interval for a population parameter.
NORM.S.INV(alpha)
Perform Hypothesis Testing
In this use case, we use the NORM.S.INV function to determine the critical value for a given significance level in order to perform hypothesis testing. The critical value helps us decide whether to reject or fail to reject the null hypothesis.
