CHIDIST(x,df)

'X' is the value for which distribution is evaluated and df is the number of degrees of freedem.

Description

This function gives the one_tailed probability of the chi-squared distribution.
It is denoted by X^2 distribution.Normally categorical datas may displayed in tables.
The X^2 static used to compare the observed value in each table to the value
which would be the expected under the assumption. The conditions of X^2 test is

1.The table should be 2x2 or more than 2x2 2.Each observations should not be dependent 3.All expected values should be 10 or greater. The test statistic is: X^2=summation(Oi-Ei)^2/Ei The degrees of freedom are: (r–1)(c–1) r =No. of rows and c = No. of columns Where: Oi-the observed value in the ith cell Ei- the expected value in the ith cell Also this function will the result as Error when 1.The x&df values are nonnumeric 2.The x value is negative or df value is not an integer 3. The df <1or df>10^10 4.Here CHIDIST=P(X>x),where X is a X^2 random variable.
