p-waarden
Het plaatje is nog grappig (zeker als je bezig bent met onderzoek), dit bericht zegt het iets duidelijker “p-values Suck“, of iets uitgebreider:

p-values are visual noise taking up precious journal space that could be filled with useful stuff such as actual estimates, effect sizes, scatter plots, confidence or credible intervals, R-code, AICs and DICs, box plots, yes sometimes even white space would be an improvement. I’m not going to rant more about p-values here, they have already been accurately characterized by others (bron)

Why multiple choice? It’s a question that’s plagued me for a long time, particularly as someone who grew up with one foot in the American and one foot in the British education system. (The former involved a lot of multiple choice testing; the latter, almost none.)
Where and when did multiple choice assessment originate? Who decided it was a good measurement of learning? How did multiple choice come to look this way? Like, why are there only four or five options in the typical multiple choice test? Why not three? Why not thirty?
How did multiple choice questions become the predominant means by which American schoolchildren are tested? And most importantly perhaps for my work: what is the relationship between multiple choice tests and technology?
