The performance of this test is compared specifically with the two tests developed earlier by Shapiro and Wilk (1965, 1972) for normality and exponentiality, respectively. This is accomplished through a power study.doi:10.1016/0378-3758(89)90115-8M.Masoom Ali...

(dry weight). From these measures, we calculated soil water content as: 100 × (wet weight−dry weight)/(dry weight). After verifying that data met assumptions of normality using a Shapiro–Wilk’s test, we analysed the effect of mussels on soil water content with a two-sidedt-test. ...
4). A Shapiro-Wilk test on the distributions of the particle’s major and minor dimension yielded that all size distributions (MP, nonsynthetic, and total particles) were non-normal distributed (p < 0.05). Therefore, median values (D50) were used to describe the data (Table 1). ...
a Shapiro-Wilk test, histograms, box plots and Q-Q diagrams [34]. If not met, a Mann-Whitney U test was performed instead of a t-test [35,36]. The nominal data were analyzed with chi-squared test or, if not indicated due to small number of samples, a Fisher’s exact test [37...

Shapiro–Wilk test was performed to verify whether data were normally distributed. Since the normality of the dataset was not verified, a Mann–Whitney U test was computed to detect any systematic bias. Spearman’s rho was computed to evaluate correlation between the two measurements. 3 Results ...
Data normality was assessed using a Shapiro–Wilk test and homogeneity of variances using a Barlett test. Effect of the different treatments (temperature, pH and time) on the physico-chemical parameters (temperature, pH and salinity) were assessed using a 3 factor linear model Anova (temperature...
