Basic Research 101: have a complete and thorough understanding of where your data are coming from, including all potential sources of error. Yet another example of AI repeatedly being used to supposedly reflect reality, and that “reality” somehow passing peer review (over and over). #DoBetter

Seriously, what is this? I’d like to thank the NYT for providing the public with a perfect example of selection bias that will now be regularly used in courses on the topic. 👎 Come on folks…

How tables like this get through peer and editorial review will forever befuddle me. Like…actually read. 🙄

Statisticians are trained in how to compute statistics, but not why to compute statistics. At least 10% of their training should be in philosophy of statistics. They should also spend 10 credits on their own empirical research project to understand how data is acually collected.

I know we are spoiled as fans of Michigan sports, but my goodness the Michigan Hockey team deserved a better fate last night.

Still, props to Denver. That is a well-coached team that was relentless all night long. And that freshman goalie is unreal.

Now, on to today’s goal of not passing out. 😴

This has arguably been the most dreadful part of this last decade of nonsense…the complete unwillingness of this body to stand up for anything. Just shameful, top to bottom.

Yes, this is one of the worst possible uses of AI that you can imagine. This practice needs to be killed with fire. And no, this is not because I work on survey methods. This is because anyone who can rub two brain cells together will realize what a bad idea this is.

This is an interesting illustration of potential bias due to non-ignorable selection: respondents from a political poll recruited by ads on Instagram reporting that their main source of information about politics is Instagram.
