| 摘 要： | 类似于物理学的"杠杆原理"和经济学的"杠杆效应",在概率统计学中也同样存在将微小变化不断放大,最终可能出现极端值的"杠杆作用"。以二项分布X~B(n,p)为例探讨了统计中的杠杆效应,并分别以社会、生活等方面的实例,具体论述阐明这一规律,从实践中得到启发与深思。

| Abstract: | Similar to lever principle in physics and leverage effect in economics, in probability and statistics there also exists leverage effect which can continuously amplify small changes to maybe extreme value.This paper discusses the leverage effect via the binomial distribution x~B（n, p） and describes the specific rule by presenting examples from various aspects including society ,life and etc, and gain inspiration ＆ contemplation from these practice. |
