Reply to comment by Frogmarsh in [OC] best-fit lines, correlations: missing persons vs 'rural-urban' – 2020 election by terrykrohe

... the upper right plot shows the 'rural-urban' values of the fifty states, ranked from more rural to more urban. This uses a definition described in the "sources" comment below.

... the bottom plot relates the top two plots: for each state its ('rural-urban', missing persons) coordinate is plotted. Is there a relationship? Do more missing persons come rural or urban states? The plot indicates that there is little (essentially none) relationship: tell me a state's 'rural-urban' value and I cannot tell you anything about that state's missing persons.

So, those upper plots do not accompany a t-test?

from "sources" comment below:

Missing persons and 'rural-urban' metrics: note that missing persons t-test indicates that data fluctuations are probably "random" in character. (t-test = 0.96)
The large difference of 'rural-urban' means (> 1 SD) for Rep and Dem states indicate that Rep and Dem states are different Sample populations. (un-reported t-test = 0.000126)

I’m guessing English isn’t your first language.
