Looks ok to me. It's mostly 20 day intervals which seem consistent but last interval is correspondingly larger for the larger date range. I think.
Well this is my point, it
looks OK. The intervals are 17 days, 20, 20 then 31. 88 days in total, why not have regular 22 day intervals? Is there significance to those specific dates? Again, they don't seem to pinpoint any significant change in trends in the UK or any of the other 5 countries. Why were just those five countries chosen to represent the rest of Europe?
So we have poor formatting and perhaps cherry picking?
I actually went and watched the report Funt took this from and the graph is only on screen for about four seconds. It was definitely not intended to be scrutinized to this extent. I'm not even disputing the basic thrust of the report, but if the headline on the graph was
"england do gooder then other europ country's"
I doubt many would let that slide. We expect a certain amount of competence in English communication from our media, but allow poor standards for Maths and Science communication. The last year has shown how important this is.
There, I think I dragged that back on topic.
