Reply to comment by malachai926 in [OC] best-fit lines, correlations: ed spending vs evangelical –– 2020 election by terrykrohe

I do not think that the "lay person" has trouble understanding the presentation:
i) Dem states residents spend $300 more per person on education than do Rep state residents
ii) Rep states are more evangelical than are Dem states
iii) for both Dem and Rep states, as the evangelical % increases, the state+local ed spending decreases

2
I do not think that the "lay person" mis-understands why a state is labelled Rep or Dem (note the "2020 election" in title)

3
I do not think that the "lay person" cares about the t-test reporting (the issue is a "tempest in a tea-pot"). I have never had a non-"lay person" ask if the t-test is the statistic or the p-value; the Mathematica documentation notes By default, a probability value or p-value is returned.

The data is a visualization of tabular data presented by the source. The data is visualized using the Mathematica function"ListPlot":

... you object to the "grouping at the state level": it is the way that the source presents the data.

There is NO analysis being done here; just data presentation. Inferences are the Reader's prerogative.

Not everyone is as thorough as I am. You seem to have a strong interest in statistics, based on the content you typically post, and if you want to succeed in the field of statistics and get noticed, you'll have to start cleaning up your presentation.

>The data is a visualization of tabular data presented by the source. The data is visualized using the Mathematica function"ListPlot":

Then you really ought to use a different function. This is just a strange way of presenting your data. You've posted very similar types of graphs here often, and it seems like they don't get much of a response. The strange presentation is probably why.

A t-test is analysis.

... yeah, the t-test is analysis

It validates the separation of Rep and Dem states into distinct Sample populations; which permits the bottom plot: correlation of ed spending vs evangelical %, considered for Rep and Dem states separately.

(that "NO" violated the "avoid absolutes" dictum)
