Ah so they did, my mistake.
I think the idea is that we all make mistakes.
I am in total agreement, we all do make mistakes, and it's refreshing when people own up to them. I guess my main question still stands though. As a top-tier data journalism outlet, why was a data QA not performed prior to analysis, or, before publishing results? And if there was data QA performed, where did it fail? It just seems that they got bit by a time crunch to publish content amid the FCC repeal and sloppy analysis was the result.
