The comparisons of TIL phenotypes were processed by Wilcoxon tests
between age, nerve invasion, vascular invasion, and axillary lymph node involvement groups.
Chi-square, independent sample t-test, Mann-Whitney U and Wilcoxon tests
were used for the statistical evaluation (p0.05).
We additionally employ a non-parametric approach using Wilcoxon tests
. Although t-tests are generally quite robust to violations of the underlying assumptions, the non-parametric approach makes fewer assumptions with respect to normal distribution of the variables.
(2) The Mann-Whitney Wilcoxon tests
for differences in independent sample medians by computing a test statistic (U-value) based on the rank of the target variable values across two groups, in our case election and non-election years.
Therefore, this study employed McNemar and Wilcoxon tests
for the performance assessment of corner detection algorithms.
The energetic returns in both of the feeding procedures were compared through paired Wilcoxon tests
for each month since data was not normally distributed.
Sign and Wilcoxon tests
analysis of the mutation-drift equilibrium for expected and observed numbers of loci with Heterozygosity excess in beef bovine breeds from Brazil.
Descriptive P values were calculated using Wilcoxon tests
and Fisher's exact tests for quantitative and categorical parameters, respectively.
Through a simulation study, they demonstrated that their modified test had greater power than the commonly used logrank and Wilcoxon tests
for detecting differences between crossing survival curves.

The Friedman and Wilcoxon tests
were used for intra- group comparisons, and the Mann-Whitney U test was used for inter-group comparisons.
