如何度量一个人的智商在同龄人中的相对位置

答案

参考答案:

解析:智力是人能力结构中的重要组成部分。衡量人的智力可以采用多种智力测验。衡量智商在相应总体的位置可以采用离差智商。 离差智商是韦伯斯勒提出的,认为人的智力的测验分数是按照常态分布的,大多数人的智力处于平均水平。离差智商是对个体的智商在其同龄人中的相对位置的度量,不受个体增长的影响,克服了比率智商的缺点。 离差智商与标准分常模的不同之处在于:一是标准分数为o,而离差智商均数为 100,即Z=X在标准分时为0,在离差智商时为100;二是标准分SD值随样本而定,而离差智商中是规定标准差为15,通过统计学原理计算智商分数,根据这个分数,结合能力分布表可以得知自己在同类群体中的位置。 离差智商是对个体的智商在其同龄人中相对位置的度量,不受个体年龄增长的影响。

    There are many advantages of becoming a professional musician. The biggest advantage is being able to

do something you love. You will have the chance to travel to many different places and meet a lot of different

people. That will open up your eyes.

    However, there are also disadvantages of being a professional musician. One of the biggest disadvantages

for most musicians is that they don't always have enough money. Most of the time, you will be looking for

jobs. Sometimes you won't be able to find a good job. Another disadvantage is the place you live in. If you

want to be a musician, you usually have to move to an area that has a lot of jobs, such as New York City.

The cost of living in these areas is usually very high. The third disadvantage is that you can't have a stable

family life. Different jobs will take a musician to different places, so most musicians are unable to have a
