Many thanks to MSU for issuing policies critical for my syllabus less than a week before the start of classes. After I finished the syllabus.

Wait until you read Infinite Jest. It's not that funny.

No, because it's hearsay. And not an exception to hearsay. Or it's an exception to an exception. But not an exception to an exception to an exception.

#T3BE (quote skeet to play) is back in business with your weekly shot to be admitted to the Bluesky Bar, have at it! Episode: podcasts.apple.com/us/podcast/t...
Question 76 of Thomas Takes The Bar Exam: A driver and a passenger were involved in a car accident. Shortly thereafter, the passenger wrote a summary of the events surrounding the accident in a journal entry. At trial three years later, the passenger is on the stand and unable to accurately recall the details of the accident, even after reviewing his written summary about the accident from his journal. 

Assuming a proper foundation is laid, may the summary of the accident be read into evidence?

Already on my syllabus for next year!

This analysis was supposed to be easy. F*** you, data.

Where is the groan button in bluesky?

It finally happened. I have a student in my grad stats course whose advisor was once my student in the same grad stats course.

Language people: my trivia team had a rhyming question where the answer was Towel Howl. We had a debate about whether those words actually rhyme. Thoughts?

Delete everything. If it's important enough, they'll email again.

Note: Despite the brilliance of this strategy, I have never been able to implement it.

Here we go again. I've reached a new level of email overload. What are your secrets for responding to the important ones while also not letting it take your whole day?

A Likert scale is always some form of Disagree to Agree rating scale. It is a type of rating scale, not synonymous with rating scale.

This is a hill I will not die on, because I have given up and have nothing left but to scream into the Bluesky void.

Underappreciated fact:

„When the entire population is measured there is no need to perform a hypothesis test. After all, there is no pop. to generalize to. When data from the entire pop. has been collected the pop. effect size is known, and there is no confidence interval to compute.“

A standard error is a standard deviation of a sampling distribution. What is a sampling distribution? That is a question for another weekend's mediation.

Don't be a hardass. At least one of your students is struggling with something major right now. No matter when now is.

How much different do two samples need to be for factorial in invariance to be meaningful validity evidence? For example, randomly splitting a sample in two and finding factorial invariance is definitely not meaningful validity evidence.

As long as the old friend is a companion during eating, not a side dish to go with the noodles. English can be a little vague.

I taught a lecture on IRT today, and I have to say that even after 25 years in the field, I don't really get it. In the absence of a causal theory of the response process, what can IRT really say about measurement and validity?

Not in Python, but I've tried several R packages and keep coming back to Winsteps.

I'd count myself in this group.

My prediction is fewer international students in higher tier programs, more students from high reputation U.S. colleges, and no change for low/mid reputation colleges.
