CHISQ.DIST Returns the chi-squared distribution.
The chi-squared distribution is commonly used to study variation in the percentage of something across samples, such as the fraction of the day people spend watching television.
CHISQ.DIST(x, deg_freedom, cumulative)
x – The value at which you want to evaluate the distribution.
Deg_freedom – The number of degrees of freedom.
cumulative – A logical value that determines the form of the function. If cumulative is TRUE, CHISQ.DIST returns the cumulative distribution function; if FALSE, it returns the probability density function.
