In simple regression, $\"r%5E2\"$ is the coefficient of determination and $\"r\"$ is the coefficient of correlation.
\n" ); document.write( "While its a simple mathematical relationship between the two, their meanings are quite different.
\n" ); document.write( "--
\n" ); document.write( " $\"r%5E2=0.81\"$ , therefore $\"r=sqrt%280.81%29=0.90\"$
\n" ); document.write( "--
\n" ); document.write( "NOTE: In multiple regresssion it is typical to use $\"R%5E2\"$ and $\"R\"$ \n" ); document.write( "
