Excel CHISQ.DIST.RT() function

Description

The CHISQ.DIST.RT() function is used to get the right-tailed probability of the chi-squared distribution.

The χ2 distribution is associated with a χ2 test. Use the χ2 test to compare observed and expected values.

For example, a genetic experiment might hypothesize that the next generation of plants will exhibit a certain set of colors. By comparing the observed results with the expected ones, you can decide whether your original hypothesis is valid.

Version: Excel 2013

Syntax

CHISQ.DIST.RT(x,deg_freedom)

Parameters

Name Description Data Type Required/
Optional
X The value at which you want to evaluate the distribution. number Required
Deg_freedom The number of degrees of freedom. number Required

Remarks :

  • If either argument is nonnumeric, CHISQ.DIST.RT function returns the #VALUE! error value.
  • If any argument is nonnumeric, CHISQ.DIST.RT function returns the #VALUE! error value.
  • If deg_freedom is not an integer, it is truncated.
  • If deg_freedom < 1 or deg_freedom > 10^10, CHISQ.DIST.RT returns the #NUM! error value.

Example : Excel CHISQ.DIST.RT() function
In the following example one-tailed probability of the chi-squared distribution, for the arguments specified in A2 and A3.

Sample Data Description
15.025 Value at which you want to evaluate the distribution.
