Age score 是148， age stanine 是 9。 Local stanine 是6,local percentile 是
72%。是不是说这个校区有28%的同龄生的分数在148以上？ |

是ITBS is norm referenced，CogAT is a ability test. 面对各种各样的ITBS 分数:
standard scores, percentile ranks, grade equivalent, national stanine，我不
知道做研究用通常都用哪一种分数？CogAT 也有好几种分数：universal scale score,
standard age score, percentile rank (grade and age), stanine (grade and age
). which one is the best for me to use for educational research? Thanks!!! |

如果是cogAT测试，会给一个“ability profile" －－ 一个Stanine score （即总共
把ability分三等，每等再分三份儿，共9，交叉对应三个方向verbal/quantitative/
noverbal）。
我觉得，比孩子的分数高低纯属无聊行为，更有意义的是根据这个测试增加对孩子特点
的认识。
读了上边链接里的“该profile孩子的学习特点”，很有收获 －－ 不同特点的孩子学
习特点不一样，美国人这方面做大量研究，我们作为家长，了解一下这些研究成果，挺
有帮助的。 （比如，有的孩子是visual thinker，有的是verbal learner。。。有的
prefer structured learning，有的适合discovery learning。。。了解一些，比招搬
我们自己的学习经验给孩子，多了一层资源）。

roughly按Stanine score的1－9， 分区越高的孩子尤其是能力均衡的，越适合
discovery learning不适应structured learning。越低的孩子，越喜欢Structured
learning。。。一直到太低的，接近idiot水平的，基本没有什么learning的能力。
不一定是聪明可能是个性？ 读读书吧小哥儿。 拿胡猜当真理doesn't help you as
much。 :)

发帖数: 1828 | 6 In probability theory, the normal (or Gaussian) distribution, is a
continuous probability distribution that is often used as a first
approximation to describe real-valued random variables that tend to cluster
around a single mean value. The graph of the associated probability density
function is “bell”-shaped, and is known as the Gaussian function or bell
curve:[nb 1]
