I need to find the first and second quintiles (20th and 40th percentiles) of the data shown here:
\n" ); document.write( "52 61 88 43 64
\n" ); document.write( "71 39 73 51 60
\n" ); document.write( "-----
\n" ); document.write( "20^ of 10 = 2
\n" ); document.write( "----
\n" ); document.write( "The 3rd element from the minimum has 20% of the data below it
\n" ); document.write( "20%ile = 51
\n" ); document.write( "-----
\n" ); document.write( "The 5th element has 40% of the data below it
\n" ); document.write( "40%ile = 60
\n" ); document.write( "==================
\n" ); document.write( "The TI-84 will rank the data but will not calculate quint's and deci's
\n" ); document.write( "===================
