Reproducibility Principles and Practices

Overview

A research project is reproducible if a different researcher can carry out the same analysis with the same data and produce the same overall result. To do so, they need transparent, detailed documentation about all of the steps in the research process and access to the tools—especially code—with which the steps were carried out. Reproducibility enables independent verification, a touchstone for all research.

There are myriad practices, often accompanied by software tools, that can help ensure research projects are reproducible. This overview workshop will help you decipher which to adopt and when to adopt them. The workshop also highlights additional benefits many of these practices confer, such as making it easier to collaborate with others. As an overview, this workshop is relatively non-technical, but provides technical references, including other DataLab workshops, for all of the practices covered.

Prerequisites

This workshop is intended for learners of at all experience levels, and may benefit learners at different experience levels in different ways. There are no prerequisites and no prior programming experience is necessary.

Responsible Data Science

Overview

Technical advancements through data science combined with the exponential increase in data has led to research breakthroughs across domains and generated entirely new industries. But, lagging behind this growth is our understanding of the evolving socio-technical landscape and ability to predict the indirect consequences of our work. While laws determine the legal parameters governing data use, data science approaches that are technically legal can still be used unethically and irresponsibly, with disastrous consequences from loss of revenue to human rights violations. Through case studies and interactive sessions, this workshop provides an overview of how to practice responsible data science by incorporating considerations of ethics, equity, and justice. We will discuss FACT (fairness, accuracy, confidentiality, and transparency) based approaches to increasing the integrity of our work in data science.

Prerequisites

There are no prerequisites for this workshop.

Data Visualization

Principles of Data Visualization from Perception to Statistical Graphics

Overview

Data visualization is a powerful tool for exploring and communicating our research findings. A good plot helps us uncover and share the patterns in our data, but creating good plots takes skill and practice. This workshop introduces concepts of design principles, visual perception, and storytelling with data. We’ll discuss the graphical elements of a plot, when to use different statistical plot types, and how to make your plots more understandable and accessible. We’ll explore some historic and more recent data visualizations as we deconstruct the principles of plotting. Learners are encouraged to bring a draft plot that they are working on.

Prerequisites

No prior experience with data visualization is necessary. This workshop is intended for researchers who are actively working with data. It covers material in a tool-agnostic way, with the intent that researchers may use it to improve their visualizations regardless of the software they use.

Network Visualization

Overview

Network science approaches are being increasingly used to explore complex interactions and the general connectivity among entities, from friends in a social network to the spread of a disease in a population. Due its complexity, network data is often explored and communicated using data visualizations.

In this intermediate R workshop we will cover how to tell useful stories with network data primarily using the statnet suite of packages and the ggraph plotting package that is compatible with much of the ggplot2 framework. In this interactive and hands-on workshop we’ll practice using these packages in R to plot one-mode and two-mode networks. As we introduce functions unique to these packages we will discuss what visualization features best suit different types of network data and research communication goals. Along the way we will cover basic data preparation steps and how to calculate (or assign) key network descriptives including centrality measures, edge attributes, and community clusters for your plots.

Prerequisites

Introduction to Spatial Statistics in R

Overview

We often see that values observed in closer spatial proximity are more alike than those from distant locations, and thus the data may not be independent. This can cause problems, and opportunities, for our analyses. In this workshop, we will discuss how spatial data can break the assumptions of common statistical methods, and work towards identifying and implementing appropriate methods in R. Specifically, this workshop will focus on the uncertainty of spatial interpolation and regression.

  • Demonstrate categorical prediction with logistic regression, and numerical predictions with a regression tree approach
  • Calculate measurements of accuracy that are applicable to the different types of models, and use cross-validation to find the model parameters that generate the best predictions
  • Interpret the results for insights about the real-world process being modeled

While this workshop features working with health data, the conceptual framework and principles discussed should be generalizable to research in other domains.

A Practical Introduction to Regression Modeling in R

Overview

Regression modeling — using input variables to predict or model the value of a response — is widely used in pretty much every field of research. Yet many graduate programs don’t include formal training in statistical modeling, and the DataLab’s office hours indicate widespread anxiety about using regression models in practice. This workshop is intended to help address that anxiety by teaching the fundamentals of using regression modeling. The emphasis is on practice and intuition, with only a small amount of math.

Prerequisites

Participants must have taken DataLab’s “R Basics” workshop series and/or have prior experience using R, be comfortable with basic R syntax, and have the latest version of R and RStudio pre-installed and running on their laptops.
