Hello I need help in understanding the Critical Value and the Chi-Squared Distribution table....
How do you describe the first row and the first column of the Critical value and the Chi-Squared Distribution table?? and what are its content mean to you?
and I would appreciate if you could explain with an example...

Thanks a lot for the help...

2. The rows of a chi-square table are the degrees of freedom.
That just distinguishes which density you are observing.

A $\chi^2_v=\Gamma(v/2,2)$ random variable.

The columns just tell you the probablity of a $\chi^2_v$ random variable exceeding that value.
