First sort the numbers into ascending order (from least to greatest):\r \n" ); document.write( "\n" ); document.write( "1,3,3,4,5,5,6,6,8,9\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Sample Mean:\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "To find the mean, add up all of the numbers and divide the sum by the number of numbers (which in this case is 10).\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "So the mean is 5\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "----------------------------------------------------------------\r \n" ); document.write( "\n" ); document.write( "Median:\r \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "To find the median, count off about 5 spaces (just take half of the size of the list, which is 10) from the beginning of the list until you hit the middle. Now count count off about 5 spaces from the end of the list until you hit the middle.\r \n" ); document.write( "\n" ); document.write( "1, 3, 3, 4, \n" ); document.write( "\n" ); document.write( "Since the middle is in between the numbers 5 and 5, add them up and divide that sum by 2.\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "So the median is 5\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "----------------------------------------------------------------\r \n" ); document.write( "\n" ); document.write( "Mode:\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "To find the mode, simply look for any repeating numbers. If there is one number that occurs more frequently than any other number, then that number is the mode.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "In this case, the numbers 5,3, and 3 repeat themselves 2 times.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "So the mode is 3 and 5. \n" ); document.write( " |
