There still seems to be a lot of confusion about significance testing in psych. No, p-values *don’t* become useless at large N. This flawed point also used to be framed as "too much power". But power isn't the problem – it's 1) unbalanced error rates and 2) the (lack of a) SESOI. 1/ >
But here's, the thing, p values and significance become useless at such large sample sizes. When you're dividing the coefficient by the SE and the sample size is in the tens of thousands, EVERYTHING IS SIGNIFICANT. All you're testing is whether the coefficient is different than zero.

It's weird - but now in Oslo, there's so many EVs that you notice the noise and the smell from individual ICE cars, and you realise how much we've been normalising it for ever. You can smell them half a street away.
And inside parking lots are just *quiet*.

It's absolutely astonishing: In just about 13 years, Norway has skyrocketed from virtually no sales of zero-emission battery electric vehicles to nearly 100% of all new passenger car purchases.

Last week, I crafted my first-ever gauge chart 🏎️ to showcase partial radial plots for our #ggplot2 [un]charted lesson on "coordinate systems"
Thanks to coord_radial(), partial circles like those are super easy now — and of course I couldn’t resist making a polished and animated version 💅📽️ #rstats

Science is plagued by bugs!
A recent study by an eleven-member research team from the Universities of Münster, Bielefeld and @uni-jena.de has provided evidence that some results of behavioural experiments with insects cannot be fully reproduced.

Ukraine is not alone.
Germany together with our European allies stands united alongside #Ukraine - and against the Russian aggression. Ukraine can build on unwavering support from Germany, Europe and beyond. Their defence of democracy & their quest for peace & security is ours.

Just a reminder that you don't have to be a statistician, or a programmer, or an analyst, or a data engineer, or a viz designer to benefit from #rstats.
It's also amazing just for basic data management tasks. Especially thanks to the #tidyverse.

Weil immer wieder zu lesen ist, dass es im Winter wenig erneuerbaren Strom gibt und Wärmepumpen darum vor allem mit Kohlestrom betrieben werden:
In den letzten Jahren war das 1. Quartal eines Jahres (in dem am meisten geheizt werden muss), meistens das mit dem der höchsten EE-Strom-Produktion.

Impactful quote from Kahneman in NYT Gino vs Bloggers article. In "Thinking, Fast and Slow" (2011) he wrote: "When I describe priming studies to audiences, the reaction is often disbelief. [...] The idea you should focus on, however, is that disbelief is not an option." Now it's the default.
