MS Excel - 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. |
| 8 | Degrees of freedom. |
