As you study these Chi Square graphs, note that the shape of the probability functions change when you vary the degrees of freedom, or df, in your experiment.
当您研究这些X平方分布图时，请注意，当您在实验中改变自由度(即df)时，概率函数的形状会改变。
In each of the graphs, the bottom axis reflects the size of an obtained Chi Square score (range showing is 0 to 10).
在每幅图中，横轴表示所得到的x平方分布值大小(图中所示范围从0到10)。
