Isi artikel

Early in the 20th century, Carl Spearman published several articles in the American Journal of Psychology on experimental methodology in general and the method of correlation in particular. They are allimportant and seminal works. The following article, "The proof and measurement of association between two things," is important because Spearman published it as "a commencement at attempting to remedy" a problem in the experimentation of his day in which "laborious series of experiments are executed and published with the purpose of demonstrating some connection between two events" but in which experimental significance is not ascertainable. This article is Spearman's explication of the adaptation of Pearson's product-moment correlation statistic to experimental results in psychology. It should be noted that Spearman made an error in his correlation formula on page 77. He defines x and y as medians rather than means. He caught it himself and made the correction in a later article. It is hard to calculate the impact of Spearman's article on modern psychology except to say that it has been immense.
