If the (observed) chi-square is greater than or equal to the (theoretical) chi-square CHIINV, the hypothesis will be discarded, since the deviation between theory and experiment is too great. If the observed chi-square is less that CHIINV, the hypothesis is confirmed with the indicated probability of error.
如果 Chi 平方观察值大于或等于 CHIINV 的 Chi 平方理论值，则假设不成立，因为理论与试验之间的偏差太大。若 Chi 平方观察值小于 CHIINV 求出的值，则假设符合规定的错误概率值。
