WorksheetFunction.ChiSq_Dist_RT Method (Excel)

Returns the right-tailed probability of the chi-squared distribution.

Version Information

Version Added: Excel 2010

Syntax

expression .ChiSq_Dist_RT(Arg1, Arg2)

expression A variable that represents a WorksheetFunction object.

Parameters

Name

Required/Optional

Data Type

Description

Arg1

Required

Double

The value at which you want to evaluate the distribution.

Arg2

Required

Double

The number of degrees of freedom.

Return Value

Double

Remarks

The χ 2 distribution is associated with a χ 2 test. Use the χ 2 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:

  • If either argument is nonnumeric, ChiSq_Dist_RT generates an error.

  • If x is negative, ChiSq_Dist_RT generates an error.

  • If degrees_freedom is not an integer, it is truncated.

  • If degrees_freedom < 1 or degrees_freedom > 10^10, ChiSq_Dist_RT generates an error.

  • ChiSq_Dist_RT is calculated as ChiSq_Dist_RT = P(X>x), where X is a χ2 random variable.
