Independent Probability

Fisher's well-known continuous method for combining independent probability values from continuous distributions is compared with an exact discrete analog of Fisher's continuous method for combining independent probability values from discrete distributions using matched-pairs t-test data. Fisher's continuous method is shown to be inadequate for combining probability values from many discrete distributions, given the continuity assumption when discrete distributions are considered. Although Fisher's continuous method does not detect a well-documented effect among distributions, the exact discrete analog method clearly detects the effect.

Automated Method

Abstract In a collaborative study, an automated method for the determination of total and direct available P2O5 was compared with the official gravimetric quinolinium molybdophosphate method, 2.023–2.025. Nine laboratories participated in the analysis of the 12 sample solutions, and the results were evaluated by the technique of closely matched pairs. The t-test showed no difference in the means of the results of the 2 methods. The estimates of the random, systematic, and total errors of the automated method all differed significantly from those of the official method when evaluated by the F-test. Further study of the automated method for P2O5 in fertilizers is not recommended.

Pheromone Dispensers

The efficiency of two types of pheromone dispensers (ECOLURE classic and ECOLURE tubus) was compared in 2008. Pheromone-baited traps were checked 13 times in 10-day intervals (this guaranteed the efficiency of ECOLURE tubus all time). ECOLURE classic trapped more beetles on average in all samples. Differences among the first 4 samples (checkings) were statistically insignificant, differences among another 9 samples were significant (used statistic tests – two choice t-test, α = 0.05 from data with normal distribution, Wilcoxon matched pairs test in the case of other data distribution).

The Fisher-Pitman and powers of ranks permutation tests are shown to provide substantial resistance to extreme values when compared with the conventional t test for analyzing matched-pairs experimental designs.

Zusammenfassung. In diesem Artikel werden die qualitativ-quantitativen Ergebnisse einer Orientierungsstudie (2000-2002) zur Wirkung und Wirkungsweise musiktherapeutischer Entspannung im (sozialtherapeutischen) Strafvollzug vorgestellt. Die Untersuchungsgruppe umfasste n = 11 Teilnehmer, die jeweils über einen Zeitraum von einem halben Jahr mit Interviews zu drei Messzeitpunkten befragt wurden. Darüber hinaus kam in jeder Behandlungsstunde ein Prä-Post-Fragebogen zur Anwendung, der statistisch mit einem t-Test für abhängige Daten analysiert wurde. Als Ergebnis ergab sich ein Modell zur besonderen Wirkungsweise und Bedeutung von Musik als Entspannungsmedium im Strafvollzug sowie ein erster Signifikanznachweis der Wirkung der musiktherapeutischen Entspannung.
