English term or phrase: a factor of two, a factor of three
However, since the mean is uncertain by a factor of two, the standard deviation is uncertain by a factor of three, and the skewness and kurtosis are uncertain by relatively wide range that allow for the selection of many plausible parametric probability distribution models.
这里的均值和标准偏差都是不确定的,但是这个by a factor of two/three,指的是什么,请热心人帮我解答一二,谢谢!

Chinese translation:不确定度为 2 倍
Explanation:
is uncertain by 是指不确定性的程度,或不确定性范围,当然可以量化。比如 uncertain by 50% (by a factor of 50%), uncertain by a factor of 2, 又如 be uncertain by ±10% 等等.

Thanks, this is the closest answer. And tons of thanks to those helpd, especially Shirley Lao, without whom I would not be able to recognize that uncertainty factor in context of t table and critical values, which tends to produce the answer I finally choose:分配臨界值扩大了两倍--a factor of two

在因子为2情况下,平均数是不确定的,所以在在因子为3情况下,标准偏差也不确定。
