The CHITEST function calculates the test for independence, the value returned from the chi-squared statistical distribution and the correct degrees of freedom. Use this function to check if hypothesized results are valid.

The CHITEST function is outdated and you will find it in the compatibility category, the function has been replaced with the CHISQ.TEST function.

Formula in cell C12:

=CHITEST(B3:C5,B8:C10)

### Excel Function Syntax

CHITEST(*actual_range,expected_range*)

### Arguments

*actual_range* |
Required. A range of data. |

*expected_range* |
Required. A range of data. |

### Comments

Independence is indicated by a low number of χ2.

The CHITEST function returns

- #N/A error value if the number of data points in the arguments doesn't match.

CHITEST function equation:

Aij = actual frequency in the i-th row, j-th column

Eij = expected frequency in the i-th row, j-th column

r = number of rows

c = number of columns

The CHITEST function function is one of many functions in the 'Compatibility' category.

Calculates the beta distribution, it represents outcomes in the form of probabilities.

Calculates the inverse of the beta distribution.

Calculates the individual term binomial distribution probability

Calculates the probability of the chi-squared distribution.

Calculates the inverse probability of the chi-squared distribution.

Calculates the test for independence, the value returned from the chi-squared statistical distribution and the correct degrees of freedom. Use this function to check if hypothesized results are valid.

Calculates the confidence interval for a population mean, using a normal distribution.

Calculates the covariance meaning the average of the products of deviations for each pair in two different datasets.

Calculates the minimum value for which the binomial distribution is equal to or greater than a given threshold value.

Calculates the F probability of the right-tailed distribution for two tests.

Rounds a number down, toward zero, to the nearest multiple of significance.

Calculates a value based on existing x and y values using linear regression. Use this function to predict linear trends.

Calculates the value from an F-test. The value shows if the variances from two data sets are not significantly different.

Calculates the gamma often used in queuing analysis (probability statistics).

Calculates the cumulative lognormal distribution of argument x, based on a normally distributed ln(x) with the arguments of mean and standard_dev.

Calculates the most frequent number in a cell range.

Calculates the percent rank of a given number compared to the whole data set.

Calculates the rank of a specific number compared to a list of numbers.

Calculates the standard deviation of a group of values.
