摘要:

SummarySequential samplingA simple survey of Walds theory of sequential sampling is given, followed by a modification of the rejection and acceptation lines. The rejection and acceptation lines of the Waldtest are lines of a constant ratio between the likelihoods of two hypotheses. The modified rejection and acceptation lines are curves, giving a constant ratio between the likelihood of one hypothesis and the maximum likelihood.The modified lines closely fit those of Wald, but ensure a natural end to the sampling before a given sample number is reached. A simple manner to evaluate rejection and acceptation probabilities of a hypothesis is still lacking, the computation now being quite inconvenient.

SummaryThis paper deals with the formulae, which make possible the calculation of quantities indicating accuracy, defined as follows and used in the “Koninklijke/Shell Laboratorium, Amsterdam”.1The repeatability r represents the greatest difference between two single results that should be considered acceptable if they are obtained within a small interval of time by a competent operator using his set of apparatus in one laboratory.2The reproducibility R(n) represents the largest acceptable difference between the mean of the nAresults of a laboratory and the mean of the nBresults of another laboratory, possibly obtained at widely different times (n=nA+nB

SummaryMatching in PsychologyIn experimental psychology the matching method seems to be one of the most promising methods. This paper deals with the matching of a series of t elements against a series of t other elements. The stated null hypothesis is: for a fixed order of one of the series each permutation of the second series has the same probability.As a test criterion in the case of one matching is defined: the number r of matches, e.g. the number of “right pairs”; for n matchings:.As the distribution offor t=3 cannot be found in literature, a table ofis given for n=I(I)30: see table I. The way of calculating and verifying is discussed.For the problem of t=3 and n 31 the degree of approximation by the normal distribution and by the Pearson's Type III distributions is examined. With the application of a correction for continuity the former gives for n=30 a reasonable approximation, the latter a very good approximation: see tabl
