Can you describe how to access this feature? I can't find anything about this online, and I asked Claude on command line and nothing comes up for "learning mode" Seems very cool.

I love the simulations. They are such a good way to learn STATS... you can still look at the theorem using math notation after, but if you've seen it work first using simulated random samples, then the math will make a lot more sense.

Hi Matt! Big fan. The first that I thought when I read this article was "How would Matt use his .assign-chain-kung-fu on this one" and I tried import pandas as pd purchases = pd.read_csv("https://www.sumsar.

Hahahah... Yes, contributing to the frequency tables. At least we're not including the symbols in question in our comments, so as not add to the imbalance!

Nice to see adults (re)learning math. It's one of the rare subjects that are guaranteed to provide "knowledge buzz" and also widely applicable. <shameless plug>For other adults interested in learning math, check out my

Very interesting. I was thinking of scaling this up by adding Sunday too, but offline mornings might be even better... I'll look into adding a schedule in the router. I think it might be helpful to program the rule to start in the desi

I'm living on my own now so I don't have experience with the group version of this. I try to be proactive if I know I'm meeting someone to remind them to call/text and not expect Signal/Telegram comms. The only thin

One thing that has been working really well for me this year is the "internet Shabbat" rule: 24 hours of no TCP/IP every week. Friday night I pull the plug on the modem + turn off data on my phone, then enjoy all of Saturday

Which JASP analyses would you recommend? I think the Bayesian linear regression is cool, but I'm not a big fan of the Bayes Factors tests, since they are very sensitive to the choice of priors. If we just switch from p-values (with 0.0

Nice. I see you cover hierarchical (multilevel) linear models, which is already a big step up from the techniques normally covered in STATS101. The general advice about measuring/comparing models also seems useful.

I've been working on a introductory STATS book for the past couple of years and I totally understand where the OP is coming from. There are so many books out there that focus on technique (the HOW), but don't explain the reasoning

I recently learned[1] that he didn't write this book. He was telling stories to Ralph Leighton, who then wrote the books, and there is reason to believe many of the stories were embellished/enhanced. I'm kind of disappointed

I like the idea of math as "self help." People don't realize it, but the more math you learn, the easier/simpler life becomes... In other words, people learn math not because they like complexity, but because they are la

Nice! The key step of the derivation is counting the "number of ways" to get the histogram with bar heights L1, L2, ... Ln for a total of L observations. I had to think a bit why the provided formula is true: choose(L,L1) * c

Not the OP, but I think I know what wongarsu is referring to. In order to make an object turn, it needs to experience an centripetal acceleration (towards the centre of rotation). This is the force causing objects to change trajectory. If t
