Scientific computing is important but mastering the skills takes time

Scientifically Sound was born out of the need to provide an online resource to conduct science that is reproducible and valid. This resource is in recognition of the fact that learning the digital skills to manage and analyse data reliably takes time and can be daunting. These concerns were echoed in the recent Nature article Scientific computing: Code alert. It

Simple rules for making research software more robust

As a new programmer, it still takes me a while to master a language and implement good coding practices. Novice and experienced programmers recognise the difficulties in learning to write code that is generalisable enough to be used in future projects, and by other users. To address these difficulties, Morgan Taschuk and Greg Wilson offer some simple tips to make

Good enough practices in scientific computing

Three years ago, Greg Wilson of Software Carpentry fame, along with fellow members of the Software Carpentry Community, published an article entitled Best Practices for Scientific Computing. This article is a great reference and covers all aspects of scientific computing. However, the paper could be intimidating to novices. To remedy this, Greg Wilson et al. recently published a follow-up paper

What are published effect sizes and study power in recent cognitive neuroscience and psychology?

Given the ongoing debate on the lack of reproducibility in many scientific fields, Szucs and Ioannidis (2017) analysed published records in cognitive neuroscience and experimental psychology journals to determine publication practices in these fields. The investigators used a text-mining approach to extract 26,841 records of degrees of freedom and t-values from 3,801 papers published between Jan 2011 to Aug 2015

Formalizing the definition of reproducibility and replicability

As highlighted in previous posts (e.g., 1, 2, 3), reproducibility and replicability are key features of scientific studies that have received considerable attention in the popular press and the scientific literature. However, as highlighted in a recent paper by Patil, Peng & Leek, there is no consensus on what these terms mean. Therefore, these authors took on the task of

What does research reproducibility mean?

Concerns about research reproducibility (or lack thereof) continue to escalate but it seems people can have quite different ideas about what research reproducibility means. In a perspectives editorial, Goodman and colleagues demonstrate concepts on reproducibility can be both precise: …reproducibility refers to the ability of a researcher to duplicate the results of a prior study using the same materials as
