\n" ); document.write( "\n" ); document.write( "For the standard deviation I keep getting confused on whether or not I'm inputting it correctly and cannot get the answer (0-2.14) squared(0) + (1-2.14) squared (.20) + (2-2.14)Squared and I just don't think I'm doing it right can you help me solve this last half please?\r

\n" ); document.write( "\n" ); document.write( "To get the Standard Deviation, first calculate the Variance\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Then the Standard Deviation is the square root of the variance.
