Pojęcie wielkości efektu na tle teorii Neymana-Pearsona testowania hipotez statystycznych

Abstract: Abstrakt. Celem tej pracy jest zwrócenie uwagi badaczy wykorzystujących metody statystyczne w analizie wyników swoich badań na pomieszanie dwóch różnych teorii testowania hipotez statystycznych, teorii Fishera i teorii Neymana-Pearsona. Zawarcie, w obecnie stosowanym instrumentarium statystycznym, pomysłów z obu tych teorii, powoduje, że znakomita większość badaczy bez chwili namysłu za prawdziwą przyjmuje stwierdzenie, iż im mniejsze prawdopodobieństwo, tym silniejsza zależność. Przedstawione zostały słabe st… Show more

“…According to Allometric Burnaby's Method (Bookstein, 1991;Reyment, 1991;Rohlf, 2010), the effect of body size and ontogenetic allometry of the specimens was removed from the data matrix by the projection of the character set on the plane orthogonal to the size vector (the first eigenvector (PC I) from the variancecovariance matrix of log 10 -transformed data). A Tukey's HSD post-hoc test was used to test for unequal N. To estimate the size effect between group means for statistically significant variables, the Cohen's d Coefficient was calculated (Cohen, 1988;Szymczak, 2015). The Cohen's d coefficient values beetwen d = 0.2 and d = 0.49 is considered a weak effect, d = 0.5 to d = 0.79 is an average effect, and d > 0.8 denotes a strong effect, however it should be interpreted with caution.…”

“…Sustainability 2021, 13, 5542 2 of 22 A literature review of this subject indicates that methods to determine the research sample size were used to test preconceived hypotheses [17][18][19][20][21][22][23]. In addition, customer requirements have been obtained using, for example, traditional methods, such as interviews or survey research [24,25].…”
