This shows all the data for the selected range of unattended correlations.  Buttons at the bottom allow you to export the data.

              
 

              

            

            

              
This is ancient psychometrics but still of some use.  For more information, see:

              https://www.psyctc.org/psyctc/glossary2/attenuation-by-unreliability-of-measurement/
              
 

              
The formula is simple:

              
 

              $$attenuatedR = unattenuatedR * \sqrt{rel_{x} * rel_{y}}$$
              
              
The short summary is that unreliability in the measurement of both variables involved in a correlation always reduces the observed correlation between the variables from what it would have been had the variables been measured with no unreliability (which is essentially impossible for any self-report measures and pretty much any measures used in our fields.)
