Make a scatter plot of the data below.
\n" ); document.write( "x: -5,-3,-3,0,1,2,5,6
\n" ); document.write( "y: -4,12,10,-6,8,0,3,-9
\n" ); document.write( "Describe the correlation of the data. If possible, fit a line to the data and write an equation of the line.
\n" ); document.write( "
\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "The linear correlation is bad, \r\n" );
document.write( "because the points don't appear to\r\n" );
document.write( "fall in a straight line.\r\n" );
document.write( "\r\n" );
document.write( "The correlation coefficient is\r\n" );
document.write( "merely -.3839067252 which in\r\n" );
document.write( "absolute value is not a good\r\n" );
document.write( "fit, for it isn't close to 1\r\n" );
document.write( "at all.  The best fitting line,\r\n" );
document.write( "called the \"regression line\"\r\n" );

document.write( "y = -.7624565469x+2.035921205\r\n" );
