Fundamentals of Data Visualization A guide to making visualizations that accurately reflect the data, tell a story, and look professional.

@kjhealy.co makes some of the best open free online guides to data visualization #datavis. Iโ€™ve always loved and used clauswilke.com/dataviz/ in my teaching and research, but this one looks even simpler and more user-friendly. Definitely worth checking out.

A black-and-white xkcd-style comic. Two stick figures stand talking.

Poster for 90 minute workshop on HOW TO DESIGN BETTER EXPERIMENTS, by Mridul Thomas & Ravi Ranjan. 

Details: September 23rd 16:00 CEST ; 14:00 UTC

Description: 

Experimental designs can make or break an experiment. A good experiment has a clear goal and efficiently uses experimental resources to achieve that goal. In this workshop, we will review what experiments are for, basic and advanced principles of designing experiments, and how to use simulations to evaluate designs before actually doing the
experiment. Weโ€™ll do a moderate amount of coding in R and so experience with this would be helpful but is not required. We intend to have small-group discussions to help participants develop their own experiments, and encourage participants to think of a specific question they would like to answer with an experiment.

@raviranjan.bsky.social & I are teaching a free online workshop with on experimental design for environmental scientists on the 23rd.

We'll focus on using simulations to evaluate how well different experimental designs help achieve your goals.

It takes patience to have a conversation about definitions as a collaboration begins... but it is important!
"Trophic state" in lakes is one of those concepts! It really makes a difference which definition we use... @mishafredmeyer.bsky.social

"If you're already trying to live low-impactโ€”recycling, avoiding plastic, limiting flightsโ€”hereโ€™s a chance to make a meaningful tech choice that aligns with those values. LLMs aren't evil by default, but theyโ€™re energy-intensive, and we need to ask whether the benefits we get justify their costs."
