There are 6 numbers, so the median is the mean of the middle two: (7 + 8) ÷ 2 = 7.5
1,1,10,11,12
6 is the median of 10 numbers
If the mean is 6 then the 5 numbers must total 6 * 5 = 30. Median is 7, so that leaves 4 numbers totaling 23. So we need 2 numbers less than (or equal to) 7 and 2 numbers greater than (or equal to) 7 which all add up to 23 and where the highest number minus the lowest number equals 10. So how about, 1,2,7,9,11 or 1,1,7,10,11 etc
The median of a set of numbers in the number that is exactly center. For example, if 1,2,3,4,5,6,&7 were a set of numbers that you were asked to find the median of, 4 would be the correct answer. To find the median, one must order the number from least to greatest and cross out all the numbers until you find the center. In such case that you are asked to find the median in a set of number that has a even amount such as 1,2,3,&4, one would have to add together 2 an 3 then divide the product by 2.
