For the pre-post-comparisons, we used McNemar's test for dichotomous nominal variables, Marginal Homogeneity test to evaluate change in multinomial data, and Wilcoxon signed rank test to evaluate differences in central tendency.
The distributions of total authors on paper according to identical responses by authors were contrasted using the Mann–Whitney U test and the Moses test of extreme reactions, to analyze differences in central tendency and dispersion, respectively.
In line with other authors (see for example Bruine de Bruin et al. 2011a) I also find that differences in uncertainty across demographic groups are smaller than those in central tendency forecasts.
The slope of the resulting psychometric function was not significantly changed, despite a significant change in central tendency.
This study has also shown that reporting gender differences from central tendency statistics only is misleading, because gender differences at the extreme tails of the distribution can be quite different from what is observed with central tendency indices.
The differences in both central tendencies and ranges of variation suggest different feeding strategies, and by implication, that the two species of Paranthropus probably had markedly different diets or foraging strategies.
To compare the difference between central tendency of results, the coefficient of determination was calculated using statistical software and an ANOVA test was performed.
If two distributions only differ in their central tendency the mean-difference plot represents a horizontal line at the respective mean difference between those two distributions.
To analyse differences between central tendencies, the Kruskal-Wallis-H-Test and Mann-Whitney-U-Test were used, which substituted parametric variance-analyses.
In vivo, individual variation in the length of this region in prairie voles is associated with differences in central V1aR patterns and variation in male-typical social behaviors [ 2, 3].
Significant differences were found both in the central tendency (Mann Whitney U test, p<0.001) and the dispersion (Moses Test of Extreme Reactions, p<0.001) between the two groups of manuscripts.
