text: find the mean and the median.? find the mean and the median. –8, –6, 4, 8, 14, 18 add the numbers all together to get 30. then divide 30 by the number of numbers you have in your set of data (6) to get 5. to get the median, you need to put the numbers in least to greatest order. they're already there, so just cross off one number on each side until you end up with one or two numbers in the middle. since there is an even number in this data, you will add the two numbers in the middle and divide the answer by 2.  4+8=12 12/2=6
