## Formula generator for CHISQ.INV FUNCTION function

The CHISQ.INV function calculates the inverse of the left-tailed chi-squared distribution. It returns the value x for which the cumulative distribution function (CDF) of the chi-squared distribution is equal to the given probability. The degrees_freedom parameter specifies the number of degrees of freedom for the chi-squared distribution.

To obtain information on the ARRAY_CONSTRAIN formula, you could ask the AI chatbot the following question: “ To get the CHISQ.INV formula for your data, you can ask the AI chatbot the following question: "What is the Excel formula to calculate the inverse of the chi-square cumulative distribution function (CHISQ.INV)?"”

## CHISQ.INV FUNCTION formula syntax

The CHISQ.INV function in Excel is used to calculate the inverse of the chi-square cumulative distribution. It returns the value at which a specified chi-square distribution has a given probability. The syntax for the CHISQ.INV function is: CHISQ.INV(probability, degrees_freedom) - Probability: This is the probability associated with the chi-square distribution. It must be between 0 and 1. - Degrees_freedom: This is the number of degrees of freedom of the chi-square distribution. It must be a positive integer. The CHISQ.INV function helps in finding the critical value for a given probability and degrees of freedom, which is useful in hypothesis testing and confidence interval calculations.

## Use Cases & Examples

In these use cases, we use the CHISQ.INV function to calculate the inverse of the chi-squared cumulative distribution. This is useful when we want to find the critical value for a given probability and degrees of freedom in a chi-squared distribution.

## Calculating Critical Value for Chi-Squared Test

### Description

In this use case, we use the CHISQ.INV function to calculate the critical value for a chi-squared test. The critical value is the value that separates the rejection region from the acceptance region in the chi-squared distribution.

### Result

CHISQ.INV(probability, degrees_freedom)

## Estimating Confidence Interval for Chi-Squared Statistic

### Description

In this use case, we use the CHISQ.INV function to estimate the confidence interval for the chi-squared statistic. The confidence interval provides a range of values within which the true population parameter is likely to fall.

### Result

CHISQ.INV(probability, degrees_freedom)

## Determining Sample Size for Chi-Squared Test

### Description

In this use case, we use the CHISQ.INV function to determine the required sample size for a chi-squared test. The sample size is the number of observations needed to achieve a desired level of statistical power.

### Result

CHISQ.INV(probability, degrees_freedom)
