First step, find the mean (average),
\n" ); document.write( "\"A=%2816%2B35%2B25%2B29%2B26%2B30%29%2F6\"
\n" ); document.write( "\"A=26.83\"
\n" ); document.write( "Next find the deviation of each value from the mean,
\n" ); document.write( "\"d%5B1%5D=16-26.83=-10.83\"
\n" ); document.write( "\"d%5B2%5D=35-26.83=8.17\"
\n" ); document.write( "\"d%5B3%5D=25-26.83=-1.83\"
\n" ); document.write( "\"d%5B4%5D=29-26.83=2.17\"
\n" ); document.write( "\"d%5B5%5D=26-26.83=-0.83\"
\n" ); document.write( "\"d%5B6%5D=30-26.83=3.17\"
\n" ); document.write( "Then square the deviations,
\n" ); document.write( "\"d%5B1%5D%5E2=117.4\"
\n" ); document.write( "\"d%5B2%5D%5E2=66.7\"
\n" ); document.write( "\"d%5B3%5D%5E2=3.4\"
\n" ); document.write( "\"d%5B4%5D%5E2=4.7\"
\n" ); document.write( "\"d%5B5%5D%5E2=0.7\"
\n" ); document.write( "\"d%5B6%5D%5E2=10.0\"
\n" ); document.write( "Sum the squares of deviation,
\n" ); document.write( "\"Sum+=+202.8\"
\n" ); document.write( "Divide by the number of samples and take the square root,
\n" ); document.write( "\"sigma+=+sqrt%28202.8%2F6%29\"
\n" ); document.write( "\"sigma+=+5.8\"
\n" ); document.write( "
\n" );
