## Correlational Example Involving COVID-19 Useful for Classes

 This Washington Post article provides an interesting example of correlationbetween 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 moreinteresting data/analysis available there.https://www.washingtonpost.com/business/2020/10/23/pandemic-data-chart-masks/?utm_campaign=wp_post_most&utm_medium=email&utm_source=newsletter&wpisrc=nl_most&carta-url=https%3A%2F%2Fs2.washingtonpost.com%2Fcar-ln-tr%2F2c4b72b%2F5f92fd6e9d2fda0efb521285%2F5ab230ae9bbc0f2b8372bb9f%2F8%2F71%2F6767f4e2dbc453527192dca03a2a33fc-Mike PalijNew York University[hidden email] ===================== To manage your subscription to SPSSX-L, send a message to [hidden email] (not to SPSSX-L), with no body text except the command.

 Note:  r = -0.85; the R^2 is provided in the article and I used a calculator toget the square root and forgot to include the negative sign (as the percentageof mask users in a state increases, the fewer one knows people with COVID-19symptoms).  Sorry about that.-Mike PalijNew York University[hidden email]---------- Forwarded message ---------From: Michael Palij Date: Fri, Oct 23, 2020 at 1:17 PMSubject: Correlational Example Involving COVID-19 Useful for ClassesTo: SPSS list <[hidden email]>Cc: Michael Palij <[hidden email]>This Washington Post article provides an interesting example of correlationbetween 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).
