We provide tests of equality of mean and median values using parametric t-tests and non-parametric Wilcoxon tests, respectively.

Furthermore, to investigate the effect of the amount of data over evaluation results, the two selected tests were more suitable, because the Wilcoxon test could differentiate performance differences using a small amount of data while McNemar's test needed large sample size as shown in Figure-1.
Statistical analyses SIGN TEST and WILCOXON TEST were performed to determine the loci number with excess Heterozygosity which was based on the theory of a locus assuming mutation-drift equilibrium from 1000 interactions and that allele status changes was under IAM and SMM.

Clearly, we are in crossing hazards setting, and the logrank test and the generalized Wilcoxon test are not necessarily sensitive to this type of alternative.

Antisaccade latencies and percent of errors were analyzed by non-parametric Mann-Whitney and Wilcoxon tests.
Faecal cortisol levels of gorillas significantly increased in enrichment phase from 17 ng/mg in control or initial phase to 31 ng/mg (Wilcoxon tests, n =48, z= -2.093, P < 0.05) (FIG.
The results of the Wilcoxon tests of Risk (C.V.) during the Quiet Period versus Lock-out Period and the Wilcoxon tests of Risk during Lock-out Period versus Post Lock-out Period are shown in Table 3.
Wilcoxon tests for mean external oblique and mean peak external oblique activity between the BS and MUS were statistically non-significant (p = 0.131 and 0.286 respectively).
Because dependent variables were not normally distributed, we conducted Wilcoxon tests to compare the number of negative and positive descriptions in the original telling phase with those in the retelling phase (see Table 1).
