The Abelian group structure of full factorial designs [PDF]
Frontiers in PsychologyThis study demonstrates formal connections between Abelian group theory and factorial experimental designs. I begin by showing that full-factorial designs are isomorphic to elementary p-groups.

The comparison of nonparametric statistical tests for interaction effects in factorial design [PDF]
Decision Science Letters, 2019 Correct application of the classical factorial F-test depends on normality and homogeneity of variance assumptions. If these assumptions are violated the type I error rate will be inflated and power of the test will be decreased.

FUNDAMENTAL CONCEPTS AND RECENT APPLICATIONS OF FACTORIAL STATISTICAL DESIGNS
Brazilian Journal of Biometrics, 2022 Factorial designs have been increasingly used in scientific investigations and technological development. The designs, through the use of matrices with all the treatment combinations, have been capable to effectively characterize the relationships between the variables of multi-factor experiments, assess the experimental variabilities, and derive ...

Raw Data Visualization for Common Factorial Designs Using SPSS: A Syntax Collection and Tutorial
Frontiers in Psychology, 2022 Transparency in data visualization is an essential ingredient for scientific communication. The traditional approach of visualizing continuous quantitative data solely in the form of summary statistics (i.e., measures of central tendency and dispersion ...

Simulation-Based Power Analysis for Factorial Analysis of Variance Designs
Advances in Methods and Practices in Psychological Science, 2021 Researchers often rely on analysis of variance (ANOVA) when they report results of experiments. To ensure that a study is adequately powered to yield informative results with an ANOVA, researchers can perform an a priori power analysis.

Factorial design and statistical analysis of smectite clay treatment by hydrocyclone [PDF]
Cerâmica, 2018 Abstract Bentonite clays are materials composed by one or more smectite clay minerals and some accessory minerals, mainly quartz, cristobalite, mica, feldspars and other clay minerals such as kaolinite. These contaminants present in clays have a large distribution of particle sizes which severely restrict their industrial applications, with the use of ...
