问题 单项选择题

样本大小适当的关键是样本要有()。

A.代表性

B.特殊性

C.相关性

D.可比性

答案

参考答案:A

解析:

本题旨在考查考生对测量心理学中常模团体中样本大小的掌握情况。一般来说,取样误差与样本大小成反比,所以在其他条件相同的情况下,样本越大越好,但也要考虑具体条件(人力、物力、时间)的限制。在实际工作中,应从经济或实用的可能性和减少误差这两方面来综合考虑样本的大小。实际上,样本大小适当的关键是样本要有代表性,从一个较小的但具代表性的样本所获得的分数通常比来自较大的但定义模糊的团体的分数要好。 【考点】:测量心理学→测验的常模→常模团体

Now and then we all get ill. Then we usually go to see a doctor. Doctors know a lot about what makes us ill. They may give us something to take. The medicine often makes us well again.

But sometimes the doctor’s medicine doesn’t work. A sick person does not get well. The pain doesn’t go away. There was such man. He was in hospital, but he wasn’t well. Then he found a new “doctor” inside himself. This “doctor” was his own sense of humor(幽默). He saw funny films. He read funny books. And he liked to learn something interesting. Laughing took away his pain. Then he was able to sleep and rest. His own happy feeling helped him to feel well again. And he told his story in a book. He said that laughing was his best “medicine”. His doctor thought so, too.

Another man was ill, and he had a terrible pain in his back. The doctors could not stop it from hurting. So the man began to “picture” his pain. In his head he “drew” a picture of a dog. He imagined(想象) it as a real dog. And it was biting(咬) his back. It was hurting him. Then the man talked softly to the dog. He put his hand on the dog’s head. He made friends with the dog. And his pain went away!

These stories may surprise you. But more and more people are getting well in this way. So call on the “doctor” inside your own head. And stay happy and well!
