In a previous post we learned how to perform an independent t-test in R to determine whether a difference between two groups is important or significant. In this post we will learn how to perform the same test using the Python programming language. Along the way we will learn a few things about t distributions and calculating confidence intervals. dataset.In

As scientists, we often want to know if the difference between two groups is important or significant. For example, you may have data on leg strength from students who came to class wearing dress shoes or running shoes. How would you decide if there was a difference in strength between these two groups? How would you quantify the size of

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

In the last GitHub tutorial, we created a repository for a project on GitHub then linked this to the project’s folder on our local computer. Linking the repository this way records the version history of our project on the Internet. When we set up the GitHub repository, we used the command line to push the local repository to the GitHub

Last year, Fang & Casadevall (2016) wrote an editorial entitled Research Funding: the Case for a Modified Lottery highlighting the chronic and severe lack of research funds and the resistance to change how these funds are allocated. While their proposal may seem drastic, especially to the lucky 10% or so who get their grants funded, the arguments put forth by

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
