Fwd: Correlational Example Involving COVID-19 Useful for Classes

Note:  r = -0.85; the R^2 is provided in the article and I used a calculator to

get the square root and forgot to include the negative sign (as the percentage

of mask users in a state increases, the fewer one knows people with COVID-19

symptoms).  Sorry about that.

This Washington Post article provides an interesting example of correlation

between the "percentage of people one knows with COVID-19 symptoms"

and "percent of people wearing masks in public" -- the unit of analysis is U.S.

states.  There is a nice scatterplot and the data used is provided in a table

(comes from Delphi CPVODCast, Carnegie-Mellon U). The R^2 is 0.72 (r = 0.85).

I have not checked the Carnegie-Mellon source but they may be more

interesting data/analysis available there.
