MOAR GULL DATA!! Also, an actual independent t test and a conceptual factorial ANOVA.

TL;DR: Birds fly away from men a bit sooner than they fly away from women. Full stop.Here is the original article, and here is a write-up from Nautilus. I love bird research. I'll get into why below. For now, let me show you how to use this example to teach three different lessons in a stats class.1. Independent t test example with a data setThe researchers shared their data.The researchers didn't analyze this data with a t test. But they did share this data visualization that looks a whole lot like one:Damn, I love the new trend of the box/violin/jitter plot.FYI: Researcher gender/the IV is labeled "gender," and how far the birds were before they flew away/the DV is labeled "FID" (flight initiation distance). Also, I love this example because the data violate the assumption of equal variance and provide a case for discussing Welch's test.2. Conceptual example for Factorial ANOVAThis example pairs well with a previous blog post featuring data suggesting that gulls take longer to…
