WHY STATISTICAL SIGNIFICANCE ALONE IS NOT A SUFFICIENT BASIS TO INTERPRET THE FINDINGS OF A STATISTICAL ANALYSIS Medical statistics plays a key role in clinical research by helping to avoid errors of interpretation due to the play of chance. It is, however, critical to understand the limits of what statistical analysis provides and interpret the findings accordingly. Statistical analysis can su...

INTRODUCTION The aim of this study was to analyse the association between the ACE ID polymorphism and aerobic capacity in a homogeneous cohort of national Asian rugby players. METHODS 17 subjects recruited during active training had their maximal oxygen uptake (V0 2 max) and ventilatory threshold (VT) measured during maximal exercise testing.

Google Earth now hosts high-resolution imagery that spans twenty percent of the Earth's landmass and more than a third of the human population. This contemporary highresolution archive represents a significant, rapidly expanding, cost-free and largely unexploited resource for scientific inquiry. To increase the scientific utility of this archive, we address horizontal positional accuracy (geore...

The linear rank test for two-sample data, which is a popular non-parametric statistical test, is extended to the case when the available data are imprecise rather than crisp. To do this, using some elements of credibility theory, we suggest a ranking method among imprecise observations and apply it to extend the usual concept of p-value leading a degree to accept or reject the null hypothesis o...
