Data was imputed in SPSS 18.0 and analysed in AMOS 18.0. Results revealed that sample sizes indeed had varying impacts on research outcomes which researchers often take for granted. The implications of these findings are broadly discussed and areas of further research suggested.Igundunasse, Alex...

Despite a growing body of research suggesting that task-based functional magnetic resonance imaging (fMRI) studies often suffer from a lack of statistical power due to too-small samples, the proliferation of such underpowered studies continues unabated. Using large independent samples across eleven tasks...
However, funnel plots of ACE D and PLA2, but not F5L, showed an inverse relationship between sample size and odds ratios for ACE D (p = 0.02) and PLA2 (p = 0.04) but not F5L (p = 0.65) by Egger's test for potential publication bias. Despite research-based genotyping of over ...
This means that if researchers in a particular field determine their sample sizes by historical precedent rather than through formal power calculation, this will place an upper limit on average power within that field. As the true effect size is likely to be smaller than that indicated by the ...
Small sample market research.Small sample market research.:Numerous market research studies are conducted with small samples of data. Many of these data are described as 'qualitative'. Researchers do not always appropriately take into account the size of the sample when drawing inferences about popula...
It is concluded that there are no principal objections to using a t-test with Ns as small as 2. A final cautionary note is made on the credibility of research findings when sample sizes are small. 展开 关键词: Sample Size Statistical Analysis Hypothesis Testing Simulation Statistical ...

The difficulty of feature extraction and the small sample size are two challenges in the field of mechanical fault diagnosis for a long time. Here we propose an intelligent mechanical fault diagnosis method for scenario with small sample datasets. This m
