Newer edit →
Line 466: {{trans\|Python}} {{libheader\|Wren-math}} The task description specifies that the Kruskal statistic is to be used (presumably the Kruskal-Wallis H test) though, unlike Julia and Python, languages which are not normally used for statistical purposes are unlikely to have this easily available. ~~Using the Wikipedia description as a guide, I've written a function to calculate and return the H value and left it at that for now.~~ Also, it's not completely clear to me how this test can be applied to lists of boolean values (whether the subject got Covid or not). I've just converted them to numbers (false = 0, true = 1) and proceeded from there. <syntaxhighlight lang="ecmascript">import "random" for Random import "./math" for Nums
