Is it just me or the barplots with uncertainty looking terribly ugly? Why not point-interval or something else?

The other day I saw a post on LinkedIn saying the Bayesianism has failed.
I felt like the time machine had worked and I was a few decades back in time.

You've made Bayesian statistics approachable. It's a lighthouse in a storm of confusion.

I've found myself struggling to choose the right vocabulary for an EDA.
In a boxplot series, can I say the median in A is higher than in B
In a scatterplot can I say the blue points are higher than the green points?
It doesn't sound right but I've seen it. Any literature about the subject?

It really isn't ok to omit the raw data from plots like these, especially when there are only ~50 study participants. And why isn't there any indication of uncertainty in these modeled fits? And don't get me started on the x-axis labels. This is THE result from this paper. Why should I trust it?

Given that this discussion can be helpful for someone else out there it would be good to give a feedback, no?

We've made a major update to the causal diagrams chapter of Causal Inference in R! Check it out to learn about DAGs! I think there's a lot in this chapter that is undercovered in other sources. #rstats #causalinference @lucystats.bsky.social @travisgerke.bsky.social www.r-causal.org/chapters/05-...

A little bit confused, are you going to make new recordings?
In any case, your material is perfect!

STATISTICAL WORKFLOW:

The structure of this course, shiraamitchell.github.io/nmaist_stati... , by Shira Mitchell and colleagues is fantastic..

In order to better integrate science into statistics and vice versa we need more teaching like this and fewer exercises that just run black box methods on black box data.
