Stat 221 T-shirts have arrived!

by Sergiy Nesterko

The class has 6 T-shirt competitions (5 finished and the final one pending) and code performance competitions based on homeworks. All winners get free T-shirts. Today, the T-shirts have arrived and the hardworking competition winners can claim theirs!

The course graphic design mastermind Sofia Hou designed two versions, and we ordered a nice variety for everyone.

There are in fact two versions of the front logos, and the lucky competition winners can pick up a T-shirt with their favorite design.

The teaching staff says all caps THANK YOU both to the competition winners, and those who weren’t yet lucky enough to get a free T-shirt. Students sometimes worked 50+ hours on their homework submissions to design better code and make them run faster for the code performance leaderboards, or came up with creative T-shirt competition entries.

In addition to the already awarded T-shirts, there are more chances to win it! We will be awarding two more T-shirts, one for comp 6, and one for pset 5 code performance leaderboard. Subject to size availability, we also plan to award T-shirts to all members of the team with the best final project presentation as determined by the audience!

We look forward to the 15+ final project presentations of work done together with the likes of Starbucks, Nationwide Insurance, eBay, Deloitte, MIT, and others.

We learned a lot in the class, and the T-shirt comps helped. We’ve learned to write better code, how to understand interactive visualization, and how to be comfortable with data-intensive problems without giving up scientific rigor. Most importantly, we learned where to go next.

The offline save stopped at the homepage, so several critiques end where the original said “Continue reading.” Kudos: 6.
