Based on ADR, both of these histories have an ADR of 2,000. Am I looking for volatility and ADR or something? Intra-ADR? Then maybe the first on should be 10000 and the second one should be 4000? Is there a name for this?
There is nothing bullshitty about the study you present. It is reality. What you intend to use that study for, may suggest further effort, but the math is what the math is.
Take a wild stab at this..... https://en.wikipedia.org/wiki/Anscombe's_quartet ...and conclude, either, "Life's a Bitch!" or, "Meh. Time to move on....."
