I have spent many a summer day at Rehoboth Beach, DE. The seagulls there were assholes. They would aggressively go after food, especially your bucket of Thrasher's french fries.
Apparently, this is a global problem, as a group of stalwart researchers in the UK attempted to dissuade gulls from stealing french fries by staring those sons-of-a-gun down. Researchers Goumas, Burns, Kelley, and Boogert shared their data. And it makes for a nice t-test example.
1. The Method section is hilarious and true.
2. Within-subject design: Each seagull was observed in the stare down and non-staredown condition
3. Their figure is a nice example of the data visualization trend of illustrating individual data points.

4. The researchers shared their data. You can download it here. The Goumas et al. supplemental data can be used as a paired t-test example, t(18) = 3.13, p = .006, d = 0.717.
