We assume that any errors in our measurements are random, meaning that it is equally likely that our measured results will be higher or lower than...
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...
That the standard deviation is larger than the average is no accident; it was our intention to allow the concentration data, of which there is a lot more than the cumulative urine data, to tell us what the measurement error must be. 3.4.2 Parameter hierarchy The hierarchical model used in...
