About this course
This course is designed to develop skills and knowledge needed to assemble, manage, visualize, analyze, and communicate about environmental data. Students will learn fundamental data science concepts and computational techniques needed to
access data from a variety of sources;
organize and reshape datasets to suit different purposes;
plot data to evaluate patterns;
assess the robustness and uniqueness of those patterns;
share their findings to different audiences.
About this course
Students will also explore how aesthetic design choices contribute to the usefulness of visualizations for telling environmental stories and best practices for making data and open and accessible for public reuse.
Why use data to build narratives?

Learning how to ask questions
“Beginners face a language problem: they can’t ask questions because they don’t know what the words mean, they can’t know what the words mean until they can successfully use the system, and they can’t successfully use the system because they can’t ask questions.”
