Halloween Histogram 2025. The rain stopped this evening and we had the temperature stayed pleasant (13C-ish). 175 trick-or-treaters visited the house... about the same as last year. #HalloweenHistogram #MathOrTreat #StatsChat #ITeachMath

For context for 4.6GW, I am often in areas I am not expert, but I know a lot about research methods and listen to expert advice. And because I prioritise being thorough in documenting sources and methods, people can review me. Unlike those trespassers that ignore existing methods & knowledge.

Where are they now: asthma

From 2015 in the Herald and in StatsChat Asthma could be cured within five years after scientists discovered what causes the condition and how to switch it off As I noted at the time: nope, and nope. Following up, the drugs in question, called calcilytics, continue to…

Random sampling > voluntary response sampling (although I don't know why this would be more important when surveying young adults).

#iteachstats #statschat ♾️
If you encounter what seems like an implausible survey finding, ask:
1. Were survey respondents selected randomly or was this an opt-in poll?
2. Could the results, especially for young adults, be driven by bogus respondents?

Q: Did the Giants beat the Rangers today?

A: The two teams averaged 2.5 runs in the game.

#iteachmath #statschat ♾️
In an electorate as polarized on so many issues as ours, the idea that an overall poll average tell us anything strategic or tactical is preposterous.

It’s like reporting sports scores in the aggregate: “The Bills and the Chiefs scored 56 points in their game last night” doesn’t tell us anything!
It'd be nice if the savvy poll-watching Dems and their consultants would start their strategy analysis by filtering out people who will never vote for them anyway.

In 2024, 94% of Republicans voted for Trump. Don't water-down support from your actual potential voters by catering to the GOP base.

Coffee nerd James Hoffman has a good video on an issue that crops up a lot on StatsChat -- totals vs means/rates -- though in his case it's about shorter vs longer espresso shots for making flat white/cappucino. From Axios: foreigners don't seem to be visiting the US as much -- this is…

Coffee nerd James Hoffman has a good video on an issue that crops up a lot on StatsChat -- totals vs means/rates -- though in his case it's about shorter vs longer espresso shots for making flat white/cappucino. From Axios: foreigners don't seem to be visiting the US as much -- this is more interesting than it sounds, since a lot of the dip must be short-notice cancellations, which are relatively difficult/expensive.

I ask this question every few months and no one ever has a good answer for me. #statschat #iteachmath
Does anyone have good examples of BTC tasks in a stats class? I can get by with thin-slicing calculus tasks but I don't know how to thin-slice most of the stats things we have to do. #MTBoS #ThinkingClassrooms

And when, over the years, my stuff has broken out into the wider media, it has often had supporting comment and context from subject matter people, or comment from @tslumley.bsky.social in the Statschat blog. Rather than me being a sole source of truth.

Some favorites from the end of semester AP Stats projects. Students chose their own statistical questions to collect data and analyze. And nothing better than a positive review from a student 😁 #mtbos #iteachmath #statschat

HELP: There must exist a @desmos.com interactive that has 1) a very small data set, 2) the option to drag a line to fit the points, and 3) a visual display of the total residual and/or the total squared residual.

Someone point me to it? I can't find one like this.
