Algebra.Com's Answer #242893 by jim_thompson5910(35256)![]() ![]() ![]() You can put this solution on YOUR website! First sort the numbers into ascending order (from least to greatest):\r \n" ); document.write( "\n" ); document.write( "31,34,34,35,40,41,44,47,48,52\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 40.6\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( "31, 34, 34, 35, \n" ); document.write( "\n" ); document.write( "Since the middle is in between the numbers 40 and 41, 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 40.5\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( "Since 34 repeats itself 2 times (which is more frequent than any other number), the mode is 34\r \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "So the mode is 34 \n" ); document.write( " |
