T分数(或T分数)是标准化分数的示例,其中平均值等于50,标准差等于10。它们是Z分数的线性变换,平均值为0,标准差为1; T分数可以通过公式T/4 50+ 10 Z从Z分数获得。T分数是方便的,因为分数低于0和高于100几乎是不可能的;事实上,99.7%的时间,T分数将位于20和80之间,因为这些界限分别是平均值以下和以上的3个标准差。早期学习的马伦量表是报告T分数的评估的一个例子。
T scores (or T-scores) are an example of standardized scores, where the mean is equal to 50 and the standard deviation is equal to 10. They are a linear transformation of Z-scores, which have mean 0 and standard deviation 1; a T score can be obtained from a Z-score by the formula T ¼ 50+ 10Z. T scores are convenient because scores below 0 and above 100 are virtually impossible; in fact, 99.7% of the time, a T score will lie between 20 and 80, because these limits are 3 standard deviations below and above the mean, respectively. The Mullen Scales of Early Learning is one example of an assessment that reports T scores.
