The meaning of STANDARD SCORE is an individual test score expressed as the deviation from the mean score of the group in units of standard deviation.
A standard score requires one to adjust raw scores so that they all have the samemeanandstandard deviation. The mean value is the average value of a data set and represents a measure of the data's location. The standard deviation represents the typical deviation between individual values and ...

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?),是描写叙述数据点在均值(mean)周围聚集程度的指标。 假设把单个数据点称为“Xi,” 因此 “X1” 是第一个值。“X2” 是第二个值,以此类推。 均值称为“M”。

If we use a z-score calculator, our value of 0.9 corresponds with a z-score of 1.282. In other words, P ( z > 1.282 ) = 0.1. Now that we have the key information (that is, the mean score, µ, the standard deviation, s , and z-score, z), we can answer our question ...
我们的工作就是从样本中估计出整体的均值(mean)和SD。因为研究应用的只是样本,所以这些估计会与整体的值未知水平的偏差。幻想情况下,计算SD的时候我们应当晓得每个家庭的分值(score)偏离整体均值的水平,但是我们手头只有样本的均值。 根据定义,分值样本偏离样本均值的水平要小于偏离其他值,因此应用样本均值减去分值失掉的...
