Although these secondary data measures have some benefits (e.g. large sample sizes, lack of survey response biases and cost), statistical tests on these data may not actually answer our underlying research questions. The present study sought to examine the reliability and validity of a set of ...

No statistical methods were used to predetermine sample sizes, but our sample sizes are similar to those reported in previous publications10,28,30. All tests except ANOVA were nonparametric without assumption on the data distribution. For the ANOVA, data distribution was assumed to be normal, but...

Data labeling, or data annotation, is part of the preprocessing stage when developing a machine learning (ML) model.
The normalized areas were used as variables for the univariate statistical data analysis. All univariate analyses and modeling on the normalized data were carried out using Metaboanalyst 4.0 (http://www.metaboanalyst.ca). Univariate statistical differences in the metabolites between two groups were ...
The Mann–Whitney U test was used to compare abnormally distributed data. Statistical significance was set at P < 0.05. Results Patient demographics The characteristics of all patients are summarised in Table 1. Overall, 209 patients (337 eyes) diagnosed at 16 years of age or younger ...
Production of secondary metabolites is controlled by a complicated regulatory network in eukaryotic cells. Several layers of regulators are involved in this process, ranging from pathway-specific regulation, to epigenetic control, to global regulation. H
Data sampling is astatistical analysistechnique used to select, manipulate and analyze a representative subset ofdata pointsto identify patterns and trends in the larger data set being examined. It enables data scientists, predictive modelers and other data analysts to work with a smaller, more manag...
