This discrepancy increases with increasing sample size, skewness, and difference in spread.
We have not observed differences in infectivity, whereas we did observe differences in spread and accumulation.
The WMW test is sensitive to distribution differences besides location [ 11] and may give a small p-value based on differences in spread even when the means and medians are equal.
The differences in spread between native and the other two groups of species were significant, but not between introduced and cryptogenic forms (Kruskal Wallis test, H = 10.371, DF = 2, p = 0.006, followed by Dunn's pairwise tests at p = 0.05).
While providing information on incident cases, the UK study also highlighted important geographic differences in spread of the disease even within the same country and raised questions about the mechanism for relative protection among the elderly.
The non-parametric WMW test, on the other hand, increases its sensitivity to distribution differences other than between means and medians, and it may detect (i.e. produce a small p-value) slight differences in spread.
Results revealed increased keratinocyte adhesion in addition to increased keratinocyte spreading and differences in keratinocyte filopodia extension on the nanotextured Ti surfaces prepared by either electron beam evaporation or anodization compared to their conventional, unmodified counterparts after 4 h.
Due to some scale differences in the responses between samples, identified as differences in spread of M-values between the arrays, scale normalization between the arrays was performed.
Cell type-specific differences in sensitivity to this phenomenon may explain why osteogenesis in hPDCs was less affected by cell density manipulations than in hBMCs, while both cell types responded to differences in spread cell area through micropatterning.
Keratinocytes from control mice reached a confluency of 45% after 38 h, compared to 4% for those from the knockout mice (Figure 7D and S4), indicating marked differences in spreading, morphology, and growth of selenoprotein-deficient keratinocytes.
