You can put this solution on YOUR website!
you are correct about the mean and the mode.
\n" ); document.write( ":
\n" ); document.write( " the median however is found by taking the middle value from an ascending order of numbers. 349+363/2=356 we had to take the 4th and 5th terms and average them since there is an even number in the group.
\n" ); document.write( ":
\n" ); document.write( "standard deviation takes some work but does have a formula
\n" ); document.write( ":
\n" ); document.write( "for this group it is 243.67\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "standard deviation =\"sum%28+sqrt%28%28x%5Bi%5D-mean%29%5E2%2Fn%29%2C+1%2Cn%29\"where \"x%5Bi%5D\" is each term in the group and n is the number of terms in the group
\n" ); document.write( "
\n" );
