As the formula shows, the standard score is simply the score, minus the mean score, divided by the standard deviation. Therefore, let's return to our two questions.1. How well did Sarah perform in her English Literature coursework compared to the other 50 students?To answer this question, ...
The Z-score, or standard score, is the number of standard deviations a given data point lies above or below mean. Standard deviation is essentially a reflection of the amount of variability within a given data set. Bollinger Bands are a technical indicator used by traders and analysts to asse...
就是 （计算的样本对象 减去 总体期望） 再除以 总体标准差。公式表示样本在总体中的位置。z-score=0表示恰好处于总体正态分布的中央位置，数值恰好等于数学期望。z-score=1就表示你问的“1 standard deviation above the average score”了...相当于“计算对象比数学期望高出一个标准差”的意思。其实...
explain what“1 standard deviation above the average score"means。能用英语回答就更好了, 相关知识点: 试题来源: 解析 "1 standard deviation above the average score" means that the observation value minus the population mean just equals to 1 standard deviation.The average score is the population ...
标准差(Standard Deviation) 标准差,缩写为S.D., SD, 或者 s (就是为了把人给弄晕?),是描述数据点在均值(mean)四周聚集水平的指标。 如果把单个数据点称为“Xi,” 因此 “X1” 是第一个值,“X2” 是第二个值,以此类推。均值称为“M”。初看上去Σ(Xi-M)就可以作为描述数据点散布情况的指标,也就...
