Ah, found it! More on the statistics fundamentals. REthinking was the keyword… This may be more on the Bayesian side than what you’re looking for.
I knew it was by @Tamas_Papp - was in a post he made as part of his “ANN: DynamicHMC 2.0” here: ANN: DynamicHMC 2.0 - #15 by Tamas_Papp
It’s “StatisticalRethinkingJulia” associated with the book Statistical Rethinking by Richard McElreath.
Dr. McElreath is Director of the Department of Human Behavior, Ecology, and Culture at the Max Planck Institute for Evolutionary Anthropology. He’s “an evolutionary ecologist who studies humans”, and as such, his lectures are engaging and fascinating!!
There’s a plethora of vids on his Tube channel here:

I’ve spent quite a few hours listening to those thanks to Mr. Papp! 
Seriously, watch one, they’re great!
