摘要
许多心理学实验所得的数据是有序数据。例如,成人记忆实验所得的依年龄为顺序的数据。通过分析这些数据,将心理活动发展过程划分成若干阶段,是在数据处理时常常碰到的问题。最优分割法是一种用于将有序数据划分成若干阶段的聚类分析(Clustering Analysis)方法。它最早由Fisher 提出,因此通常又叫做Fisher 最优分割法(参见[1],但本文中有些符号的含义与它不回)。用这种方法分析有序数据,较目前常用的F 考验和t
In this paper,together with itsapplication in psychology,Fisher's clu-stering method for ordered samples(namely,optimal ovision method)ispresented,taking fr example the dataprocessing of Smith's experiment onthe mastering of words in children,ofthe experiment made by the Instituteof Psychology on the memory develop-ment of adults in the Beijing area,andof Ebbinghaus' forgetting curve,etc.An algorithm to reduce storage andcomputation time is introducedin brieffor the implemention of the optimaldivision method with(microprocessors). The function of the optimal divisionmethod in psychology is discussed byway of a comparison with F-test andt-test.
