平均或居于中位的行为模式 Explanation: http://zh.wikipedia.org/wiki/中位數 Average和median在这里都是统计学的用词,后者指的是“中位数”或“中位值”。例如,采样100个,总起来除以100,得到的数值是“平均值”,但若再确定100个采样中最接近平均值的确实数值,那个数值就是“中位数”(median)。 -------------------------------------------------- Note added at 55 mins (2008-09-14 11:49:26 GMT) -------------------------------------------------- 维基的解说虽然简略些,但已经够清楚了。所有的研究调查,评估调查结果都会用到median,以确定统计分布状况。 |

统计平均或统计中值代表的行为模式 Explanation: normal在这里来自统计学中的正态分布,也叫钟形分布,目的是从随机事件中发现某一事物或事件发生的内在特征甚至规律。从分布曲线与横坐标之间围起来的面积看,平均值或中间值(周围)所对应的面积占百分比最高,因而用来代表大多数人的行为模式以做参考。 |
