摘要:

Many standard test and estimation procedures require the computation of the sample standard deviation. It is, however, often possible to replace the standard deviation by the more easily computed sample range without appreciably reducing the precision of the method. This paper discusses range methods which have been suggested in the statistical literature in connection with problems about the means and variances of one or two normal populations.

摘要:

This paper gives a geometric illustration of some of the commonest identities in the algebra of the sum of squares. The method is essentially the construction of squares of the various numbers and their means. These pictures provide us with a visual representation of what the identity says. The method is later extended to represent the identities concerning the sum of products by constructing rectangles.

摘要:

This article is addressed mainly to applied workers, and is devoted to giving as complete a picture as possible of the techniques and assumptions involved when correlations are estimated from biserial data. The exposition is nontechnical in the sense that mathematical proofs are omitted and numerous examples are given. The related theoretical material is contained mainly in two recent articles by the author [11, 12].
