Raw Data Visualization for Common Factorial Designs Using SPSS: A Syntax Collection and Tutorial [PDF]
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 ...

Factorial Designs Help to Understand How Psychological Therapy Works [PDF]
A large amount of research time and resources are spent trying to develop or improve psychological therapies. However, treatment development is challenging and time-consuming, and the typical research process followed—a series of standard randomized ...

Unbalanced 2 x 2 factorial designs and the interaction effect: a troublesome combination. [PDF]
In this power study, ANOVAs of unbalanced and balanced 2 x 2 datasets are compared (N = 120). Datasets are created under the assumption that H1 of the effects is true. The effects are constructed in two ways, assuming: 1.

QANOVA: quantile-based permutation methods for general factorial designs [PDF]
Population means and standard deviations are the most common estimands to quantify effects in factorial layouts. In fact, most statistical procedures in such designs are built toward inferring means or contrasts thereof.

A Bayesian approach to the selection of two-level multi-stratum factorial designs [PDF]
In a multi-stratum factorial experiment, there are multiple error terms (strata) with different variances that arise from complicated structures of the experimental units. For unstructured experimental units, minimum aberration is a popular criterion for
