摘要
平均值和标准偏差是误差理论和数理统计理论中的两个核心问题。平均值的计算方法虽然简单,但是,它的内涵却并不是十分简单。本文以通俗的语言对平均值的本质作了深入浅出的介绍。
The average value and standard deviation is the two key problems in the error theory and mathematical statistics theory. Although the calculation method of the average value is simple but its meaning is recondite.This paper introduces the principle of the average value in detail with simple words.
