Traditionally you’d express this with an r sq instead of just eye-balling trend lines…

Well R-sqr would be if one was a model of the other. This would just need a correlation coefficient.

And confidence intervals.

Confidence intervals for what

Deviation from mean, obv.

Nope, true story. My advisor got it from his advisor so it’s been around

This is the best comment

Completely agree with above. Also though, you would loosely expect to see a 'google' trend of this nature follow any topic of interest. Certainly not a leading indicator.

This sub is really more of a “data based entertainment” subreddit at this point.

To be fair stats are pretty ugly to most people, wouldn’t really fit the theme to be stat heavy.

Assuming it's a linear relationship
fasnoosh t1_j9adno2 wrote
You’d want to create a scatterplot, with one data point per x value on the line chart, and in the scatterplot, x & y axis represents each trendline color. Then, you could fit that with a model (maybe linear regression), and from that model you could get some metrics out of it, like R squared & confidence intervals
