We are pleased to announce the dataset to be used in the Data Challenge Expo 2025. A special thanks to Hadley Wickham (Posit) for suggesting we take another look at a now well-known data set first used in the 2009 challenge. As Hadley wrote: "it might be fun to repeat the 2009's with 16 years more data and 16 years of improvement to computers & tools." So, check out the Data Challenge Expo website (https://community.amstat.org/dataexpo/home) for details, code, research questions, and more.
Participants in the 2025 Data Expo Challenge will develop a research question to explore, analyze, and visualize flight arrival and departure data for all commercial flights across the USA. Uncover new insights in the skies as we revisit the 2009 Data Expo, a past favorite. With 16 years more data, this rich dataset offers endless possibilities for creative exploration. This is your opportunity to uncover insights and tell a compelling story through data visualization and innovative analysis. Participants must use the flight data and at least one additional dataset.
