Z-score的公式为:z=(x-μ)/σ;其中z为标准分数;x为某一具体数据的值,μ为该组数据的平均数,σ为该组数据的标准差,即 Z-score的计算过程如下: 1、在雅虎财经网站上下载标准普尔500指数(^GSPC)2018-4-2至2019-4-1这一年期间的每日收盘价,将经调整后的收盘价整理如下: 2、用公式AVERAGE(W2:W252)计算每...
Using the NORM.S.INV function in Excel for Z Score calculationThe NORM.S.INV function in Excel is not used to calculate the Z Score directly from a data point. Instead, it is used to find the Z value (also known as the Z Score) corresponding to a given cumulative probability in a ...
1. 将原始分数按从小到大的顺序排列。2. 计算每个原始分数对应的累积频率（累积频率表示小于等于该分数的观测值比例）。3. 根据累积频率可以得到每个原始分数对应的百分等级（百分等级等于累积频率乘以100）。计算Z分数（Z-score）的步骤：1. 计算原始分数的平均值（μ）和标准差（σ）。2. 对于每个原...
