\n" ); document.write( "My recommendation would be that You become familiar with either a TI Calculator
\n" ); document.write( "or Excel functions/Stat Tool for making Your statistical calculations.
\n" ); document.write( "For ex:
\n" ); document.write( "using Excel CORREL function:
\n" ); document.write( "entering Data Given...
\n" ); document.write( "correlation coefficient = \"-.9537\"
\n" ); document.write( "Using www.easycalculation.com/statistics/regression.php

\n" ); document.write( "y = 96-8.8x
\n" ); document.write( "final grade of a student who misses 3.5 days
\n" ); document.write( "y = 96-8.8(3.5) = \"65.2\" \n" ); document.write( "
