CHIDIST function

PRO

In Jspreadsheet Formulas Pro, the CHIDIST function is used to calculate the one-tailed probability of the chi-squared distribution. In simpler terms, it helps you determine how likely an observed distribution is due to chance, based on a chi-squared statistic. This function can be beneficial in statistical analysis, particularly in testing hypotheses. You need to provide two arguments to use this function: the value of chi-square statistic and the degrees of freedom.

Documentation

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

Syntax

CHIDIST(x, degrees_freedom)

Parameter	Description
`x`	The value at which you want to evaluate the distribution.
`degrees_freedom`	The number of degrees of freedom of the distribution. Must be a positive integer.

Behavior

The CHIDIST function calculates the right-tailed probability of the chi-squared distribution. The function takes two arguments: x (the value at which you want to evaluate the distribution) and deg_freedom (the number of degrees of freedom).

If either of the arguments is non-numeric, CHIDIST returns a #VALUE! error.
If the deg_freedom is less than 1 or greater than 10^10, CHIDIST returns a #NUM! error.
If x is negative, CHIDIST returns a #NUM! error.
Empty cells are treated as zeros.
Texts and boolean values are not valid inputs and would result in a #VALUE! error.
The function propagates any error from cells referenced in the arguments.

Common Errors

Error	Description
#VALUE!	If either of the provided arguments is non-numeric, a `#VALUE!` error is returned.
#NUM!	If the deg_freedom is less than 1 or greater than 10^10, `CHIDIST` returns a `#NUM!` error. Also, if x is negative, `CHIDIST` returns a `#NUM!` error.

Best practices

Ensure that both x and deg_freedom are non-negative values to avoid #NUM! error.

degrees_freedom must be a positive integer. Using non-integer values may return a result, but it's statistically incorrect.

Be aware that CHIDIST calculates the right-tailed probability. If you need the left-tailed probability, consider using other functions like CHIINV.

Always check the data types of the arguments you are passing to avoid unexpected #VALUE! errors.

Usage

A few examples using the CHIDIST function.

CHIDIST(2.5, 4) returns 0.6446
CHIDIST(6, 8) returns 0.6472
CHIDIST(1, 1) returns 0.3173
