Calculates the left-tailed chi-squared distribution, often used in hypothesis testing.

Sample Usage




CHISQ.DIST(x, degrees_freedom, cumulative)

  • x - The input to the chi-squared probability distribution function. The value at which to evaluate the function.

    • Must be a positive number.

  • degrees_freedom - The number of degrees of freedom of the distribution.

  • cumulative - Logical value that determines the form of the function.

    • If TRUE: CHI.DIST returns the left-tailed cumulative distribution function.

    • If FALSE: CHI.DIST returns the probability density function.


  • degrees_freedom is truncated to an integer if a non-integer is provided.

  • degrees_freedom must be at least 1 and may not exceed 10^10.

  • x and degrees_freedom must be numeric.

Suppose you want to test the fairness of a 6-sided die:

  • From several rolls, you obtain a chi-squared statistic of 12.3.

  • The number of degrees of freedom is 6 - 1 = 5.

  • We will evaluate the chi-squared distribution with 5 degrees of freedom when x equals 12.3.
