Did you read classroom connections?

Over at Briefed by Data I’ve started doing a classroom connections post. I include material that I think could be used in a classroom somehow. The topics will vary based on what I’ve run into. This past one includes a range of math being used, from calculus and statistics to modeling to data science. The graph here is from an article that did hierarchical clustering, and the data is available. Click the link if you are looking for classroom ideas.
