Approx Chi Square. Therefore it is important to check that the counts are large enough to result in a trustworthy p value. An accurate normal approximation for the cumulative distribution function of the chi square distribution with n degrees of freedom is proposed.
Fortunately the chi square approximation is accurate for very modest counts. The results are in. Therefore it is important to check that the counts are large enough to result in a trustworthy p value.
Or have you found something significant.
The results are in. In these results the p value is 0 8853. Fortunately the chi square approximation is accurate for very modest counts. Chi n q 2 approx frac 1 2 z q sqrt 2 n 2 your variation can be derived from the asymptotic result sqrt 2 chi n 2 sqrt 2 n 1 overset text approx sim text n 0 1 which is also asymptotically valid since the effect of the minus one is vanishing as n rightarrow infty.
