Getting Started With Surveys

Surveys can be an extremely useful tool for gathering information from individuals and groups. They are used across disciplines and industries to help researchers learn more about populations and gain actionable insights. I’ve done extensive survey research in nonprofit and industry settings, using these data to improve programs, make changes to technology, design communications plans, make content acquisition decisions, and much more. In this blog post, I’ll focus on one of the most important parts of survey research — planning....

Reduce, Reuse, Recycle: Practical strategies for working with large datasets

Angela Liu

When the size of your datasets start to approach the size of your computer’s available memory, even the simplest data wrangling tasks can become frustrating. Suddenly, reading in a .csv or calculating a simple average becomes time-consuming or impossible. As students or researchers, accessing additional computing resources can be costly or is not always an available option. Here are some principles and strategies for reducing the overhead of your dataset while keeping the momentum going. The code mainly focuses on reading csv files - a very common data format - into Python...
