The ChiSquare1D.php class needs access to the Chi Square methods in Distribution.php to compute the tail probability of an obtained Chi Square value.
php类必须能够访问Distribution.php中的 X平方分布方法，以计算所得到的 X平方分布值的尾数概率。
In general, the probability of obtaining a large Chi Square value goes down as you increase the number of response options in your study.
通常，当您在实验中增加回答选项的数目时，获得较大x平方分布值的概率会下降。
So, as you add response options, the statistical probability of obtaining a large Chi Square value should increase and the probability of obtaining smaller Chi Square value decreases.
因此，当您增加回答选项时，获得大的x平方分布值的统计概率应该增加，而获得较小x平方分布值的概率会减少。
Just to confirm this conclusion, you can compare the obtained Chi Square value to the Critical value.
为了确认这一结论，可以用获得的x平方分布值与临界值进行比较。
The obtained Chi Square value is re-expressed as a tail probability value -- in this case, 0.02.
获得的X平方分布值被重新表示成尾数概率值 —在本例中是 0.02。
The obtained Chi Square value is re-expressed as a tail probability value -- in this case, 0.02.
获得的X平方分布值被重新表示成尾数概率值 —在本例中是 0.02。
