In fact, none of these results are statistically significant, i.e., they're just as likely to be caused by chance as by real differences in the treatments.
事实上，这些结果没有一个在统计上是显著的，也就是说它们由偶然导致或由处理水平间真正差异导致的可能性相等。
For example, are the differences in yield produced by different work teams statistically significant?
