Long considered a “soft” area of practice, more art than science, humanitarianism and adjacent professional fields increasingly rely on using data to design, garner support for, and evaluate their initiatives. Data visualization comprises a powerful set of tools and techniques used to explore and present information. Combined with program research skills and fluency in statistics, it can help us understand problems we confront, interventions we craft to solve them, and the effects of those interventions. It can help us to communicate, telling visual stories that can convince our target audience, be they colleagues, policymakers, funders, or the general public. This course is designed to cultivate basic data visualization and statistical skills that can provide a solid professional advantage on the job market.
