What in the world is up with that fake trendline? it's like a regression line escaped from some neighboring graph and is just causing a ruckus, rudely. I mean: That is just wild.
As news outlets are creating increasingly complex data analysis and visualization projects, we should start demanding fully reproducible analysis scripts with every story.https://twitter.com/DataProgress/status/1076886420843831298 …

You've got to wonder who looked at that and said "yup, looks good!"

Or at least a methods section ;)

Methods: We gave the original idea and raw data to our in-house data science specialist, who generated the final figure.

The problem with "data science" is they receive just enough statistical analysis training to be dangerous, especially since almost no data scientists are proficient in the context of the source material

I can’t figure out where the heck that “trendline” came from. Even if I try things like excluding all the blue dots so we’re only looking at the ones Trump won, it still looks like it should be far flatter than that. Did they...weight things by something like residual^10?
-
If it wasn't simply drawn by hand then they must have done something like regress x against y but then plot it as y against x.

Good idea, but maybe we should start providing them ourselves first

Well, some of us are.

Perhaps but it’s definitely not the norm unfortunately

The flaw common to all software-based analysis, whether SPSS, Excel, Python, or even R, is that users can be accomplished enough to produce charts that look visually impressive but that don't have statistical validity.

@BuzzFeed has a nice GitHub of data & code accompanying articles;@j_perkel makes his own work reproducible; and@TheEconomist also has some nice work uphttps://twitter.com/futuraprime/status/1049600887268757504 … -

I will probably never understand why there is even the need for a trendline for such noisy data. What value are they adding to the chart by adding it in?

It is always suspicious when the intercept term is nearly negative infinity.

Even if that trend line was somehow right I'd like to see the r-squared!
