Given values are 7, 19, 19, N, 15\r
\n" ); document.write( "\n" ); document.write( "Their mean is given to be 13.\r
\n" ); document.write( "\n" ); document.write( "Which means the sum of the given values divided by 5 = 13\r
\n" ); document.write( "\n" ); document.write( "==> (7 + 19 + 19 + N + 15)/5 = 13
\n" ); document.write( "==> (60 + N)/5 = 13
\n" ); document.write( "==> 60 + N = 65 [multiplying by 5 on both the sides]
\n" ); document.write( "==> 60 + N - 60 = 65 - 60
\n" ); document.write( "==> N = 5\r
\n" ); document.write( "\n" ); document.write( "So the unknown value = 5.\r
\n" ); document.write( "\n" ); document.write( "Mean is nothing but the average of the given values.\r
\n" ); document.write( "\n" ); document.write( "To find the median we first arrange these values in one order.
\n" ); document.write( "That is ascending or descending.
\n" ); document.write( " ==> 5, 7, 15, 19, 19\r
\n" ); document.write( "\n" ); document.write( "The middle value is called the median
\n" ); document.write( "Here the median = 15.\r
\n" ); document.write( "\n" ); document.write( "Mode is the most frequantly occured value.\r
\n" ); document.write( "\n" ); document.write( "Here 19 is repeated and so mode = 19.\r
\n" ); document.write( "\n" ); document.write( "Good Luck!!! \n" ); document.write( "
