问题 单项选择题

在百分位常模中,应用最广的表示个体在常模团体中所处位置的是()。

A.百分点

B.百分等级

C.四分位数

D.十分位数

答案

参考答案:B

解析:本题旨在考查考生对测量心理学中百分等级概念的掌握情况。百分位常模包括百分等级和百分点(percentilerankandpoint)、四分位数(quartiles)和十分位数(deciles)。其中,四分位数和十分位数只是百分位数的两个变式,其含义相似。百分位数是将量表分成100份,而四分位数是将量表分成四等份,相当于百分等级的25%、50%和75%,十分位数则是将量表分成十等份,1%~10%为第一段,91%~100%为第十段。百分等级是应用最广的表示测验分数的方法,是指原始分数低于某个分数的人数百分比,且只取整数值,也即分数高过多少百分比的人数,旨在比较该范围相对于全体资料的大小,百分等级可以指出的是个体在常模团体中所处的位置,百分等级越低,个体所处的位置就越低。而选项A的百分点也称百分位数,与百分等级的计算方法不同。百分等级是计算低于某测验分数的人数百分比,而百分点则是计算处于某一百分比例的人对应的测验分数是多少。

Robert is nine years old and Joanna is seven. They live at Mount Ebenezer. Their father has a big property. In Australia they call a farm a property.
