AbstractWe performed an empirical study of the perceived quality of scientific graphics produced by beginning R users in two plotting systems: the base graphics package (“base R”) and the ggplot2 a...

The R programming language is built on an ecosystem of packages, some that allow analysts to accomplish the same tasks. For example, there are at least two clear workflows for creating data visualizations in R: using the base graphics package (referred to as "base R") and the ggplot2 add-on package based on the grammar of graphics. Here we perform an empirical study of the quality of scientific graphics produced by beginning R users. In our experiment, learners taking a data science course on th...

Objective To determine whether the rate of sentinel lymph node (SLN) dissections that do not yield a lymph node on pathological analysis (9empty packet dissection9) changes with increasing surgeon experience in the setting of patients undergoing minimally invasive hysterectomy and SLN mapping using indocyanine green dye for endometrial cancer. Methods All patients undergoing SLN mapping using indocyanine green dye at the time of minimally invasive hysterectomy for endometrial cancer or complex a...

Git and GitHub are common tools for keeping track of multiple versions of data analytic content, which allow for more than one person to simultaneously work on a project. GitHub Classroom aims to provide a way for students to work on and submit their assignments via Git and GitHub, giving teachers an opportunity to teach these version control tools as part of their course. In the Fall 2017 semester, we implemented GitHub Classroom in two educational settings--an introductory computational statis...

Most researchers do not deliberately claim causal results in an observational study. But do we lead our readers to draw a causal conclusion unintentionally by explaining why significant correlations and relationships may exist? Here we perform a randomized study in a data analysis massive online open course to test the hypothesis that explaining an analysis will lead readers to interpret an inferential analysis as causal. We show that adding an explanation to the description of an inferential an...

There has been an increasing concern in both the scientific and lay communities that most published medical findings are false. But what does it mean to be false? Here we describe the range of definitions of false discoveries in the scientific literature. We summarize the philosophical, statistical, and experimental evidence for each type of false discovery. We discuss common underpinning problems with the scientific and data analytic practices and point to tools and behaviors that can be implem...

Graph theory is increasingly being used to study brain connectivity across the spectrum of Alzheimer's disease (AD), but prior findings have been inconsistent, likely reflecting methodological differences. We systematically investigated how methods of graph creation (i.e., type of correlation matrix and edge weighting) affect structural network properties and group differences. We estimated the structural connectivity of brain networks based on correlation maps of cortical thickness obtained fro...
