The Abelian group structure of full factorial designs [PDF]

Frontiers in Psychology
This 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.

Reduce or not reduce: a practical guide to calculate sample size for various experimental design in studies involving animals [PDF]

Frontiers in Pharmacology
The ethical imperative to reduce the use of animals in scientific experimentation has become increasingly prominent, driven by societal expectations, regulatory frameworks, and concerns regarding the reproducibility of preclinical research.

An experimental evaluation of a loop versus a reference design for two-channel microarrays [PDF]

, 2004
Motivation: Despite theoretical arguments that socalled "loop designs" of two-channel DNA microarray experiments are more efficient, biologists keep on using "reference designs".

Statistical isomorphism of three-level factional factorial designs

, 2006
From a statistician's standpoint, the interesting kind of isomorphism for fractional factorial designs depends on the statistical application. Combinatorially isomorphic fractional factorial designs may have different statistical properties when factors ...

Advanced row-column designs for animal feed experiments

Indian Journal of Animal Sciences, 2023
Inappropriate statistical designs may misinterpret results of animal feed experiments. Thus complete statistical designs can make animal feed research more appropriate and cost effective.

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 ...
