Err..looking at a normal if there’s symmetry around the center.

I don’t know a name for it, but your point about the median is well taken. These are sort of like looking edgewise at a normal distribution slice, and the mean is a parameter of the normal, so maybe that? Both might be interesting too.

Is there a version of the box plot that slices along empirical rule boundaries? 68%, 95%, 99%? I’m just trying to think of natural cut points.

One big difference is that the traditional Tukey box plot shows ¹⁄₄ slices as well as the IQR (Q₃ – Q₁) which is relevant to outliers. The quintiles plot is better at showing peaks maybe because it has smaller bins. Would a sextile plot do even better for skewed distributions?

Do you have a copy of Bjorn Lomborg’s 𝘛𝘩𝘦 𝘚𝘬𝘦𝘱𝘵𝘪𝘤𝘢𝘭 𝘌𝘯𝘷𝘪𝘳𝘰𝘯𝘮𝘦𝘯𝘵𝘢𝘭𝘪𝘴𝘵? If he had your chart, he’d say “Oh look, everything’s fine”. It was quite controversial 25 years ago when it came out. You should look for it and maybe get some inspiration.

Twice you’ve written “felon” with the F and E capitalized. Why?

I hate that you use the word spook. Here in the southern US, this is a racially charged term that jolts me out of your posts.

Nice as usual Xan. Does it bother you at all that people are disagreeing more and more with the statement, yet the curve is rising?

I had cats and dogs throughout my youth and I don’t ever remember any of them ever going to the vet for any reason, including that time when our cat Clem had his rear leg swell up from a snakebite.

It’s appealing to humans’ basest emotions. Reptile brain kinda stuff. Hating someone that’s not like you is the easiest thing in the world, and too many people don’t want the slight work to overcome it.

I once had a suet feeder on my porch, and some nights the raccoons would stack themselves six high to get at it.

I can’t tell if he’s drawing the jitter based on the data—the np.normdist() call is cut off—but he’s certainly implying a specific variation with that jitter.

It’s like he’s trying to stretch one dimension into two. I know that’s not exactly what he’s doing but it feels like that.
