It is well known that the central limit theorem enables the t-Test and ANOVA to be fairly robust to the assumption of normality. A question that invariably arises is, “How large does the sample size have to be?” A popular rule of thumb answer for the one sample t-Test is “n = 3...
Sample sizeStandardized effect sizeThe concepts and implementation of standardized mean differences and minimum effect tests have been emphasized in ANOVA. The corresponding processes and implications are, however, not yet well explicated in the context of ANCOVA. To enhance the usefulness of ANCOVA, ...
Full size table For the group with slight incontinence at baseline, there was also a significant correlation, Spearman rho − 0.318 (p < 0.001), between the PGI-I and change in the ICIQ-UI SF score. The one-way ANOVA showed that there was significant differences within the ANOVA ...
The repeated measures ANOVA computed on the absolute percent errors revealed no main effects of profiling method in either squat variation (p = 0.88 and 0.20, for the SMCS and FWECS, respectively). As can be seen in Figs. 1 and 2, the Bland–Altman analysis showed increased accuracy ...
Kelley's (1967, 1973) suggestion that the attribution process can be compared to the statistical procedure of analysis of variance (ANOVA) was investigated. More specifically, I examined whether person and entity attributions vary as a f... F Försterling - 《Journal of Experimental Social Psyc...
However, we believe that our statistical analysis presented power of comparison in relation to the score used since it was necessary for the sample size to be at least 16 patients per study group and for this to have been calculated with power of 90%, and type I error (a) of 0.05. ...
Viral capsid widths were also similar to those reported for the global upper oceans [36]. While viral capsid width did vary significantly among all samples (global ANOVA p < 0.001), there was not an evident trend in overall capsid widths with depth or between stations (Supplementary Fig....

Full size table Regression analyses (ANOVA) were carried out to obtain mathematical models (Table 5) that better describe the relation between the indepe...
Despite their substantial and instanta- neous 15NO3À production and the apparently high correlation between 15NO3À and time (r240.90), the low degrees of freedom resulted in slightly higher P-values (0.07–0.20) from one-way ANOVA in a few experiments—St 225: 85 m and 118 m; St ...
