陪审团成员间的预期智商差异
最近网上有人讨论智商差距过大会导致两人难以沟通。有研究证实了这一现象,但并非无法克服,需要刻意努力。有人反驳这一观点,指出陪审团成员之间的预期智商差异其实并不大。本文从统计角度分析了一个随机选出的陪审团中,成员间智商差异的数学期望值。

A new general nonlinear dynamical model predicts potential population crisis scenarios, suggesting that future demographic trends could lead to significant societal and economic challenges if current patterns continue.
In a randomly selected jury of 12 people, the expected highest IQ is about 117 and the lowest about 83, giving a spread of roughly 34 points, based on a normal distribution with mean 100 and standard deviation 15.
The article discusses how to calculate the expected range for samples from a normal distribution, explaining that the expected range depends on sample size and is expressed as a constant multiple of the standard deviation. It presents tables and approximations for these constants, known as d₂ values, which are used in quality control and statistical process control.
