median(6,9,7,12,12,4,9,6) = 7

As there are 6 numbers, the median is half way between the middle numbers, or (7+9) / 2 = 8
To find six numbers with a range of 2 and a median of 4, we can start by placing the median 4 in the middle. Since the range is 2, the numbers on either side of the median will be 2 and 6. This leaves us with the numbers 2, 4, 4, 4, 6, and 6. These six numbers have a range of 2 and a median of 4.
When there is an even number of data items the median is the mean average of the middle two. → median of {2, 3, 4, 5, 7, 9} = (4 + 5)/2 = 9/2 = 4.5
1, 2, 2, 3, 4, 4, 5, 7, 8 Mean: 4 Median: 4 Mode: 2 and 4

(2 + 2 + 3 + 5) / 4 = 12 / 4 = 3
The median is 3.5, the number halfway between the two middle numbers when they are in order.

Assuming the set is 4 4 0 3 2 5, the median would be the center number of the ordered set 0 2 3 4 4 5, which would be between 3 and 4, so the answer is 3.5
It is 11.5
it is 3
The median is the middle value. 2 , 2 , 3 , 4 , 5 Median = 3
Let first COI=n=3 second COI=n+2=5 third COI=n+4=7 (n)(n+2)=n+4+8 check: n^2+2n=n+12 n^2+n-12=0 -n-12 -n-12 -4^2+(-4)-12=0 n^2+2n-n-12=0 16+(-4)-12=0 n^2+n-12=0 12-12=0 (n+4)(n-3)=0 0=0 n+4=0 n-3= 0 n^2+n-12=0 -4 -4 +3 +3 3^2+3-12=0 n=-4 n=3 9+3-12=0 reject 12-12=0 because is negative and it needs to be positive 0=0
It is: (4+5)/2 = 4.5
8. In order: 4, 6, 7, 9, 10, 12 6 data items so median is mean of middle two: median = (7+9)/2 = 8.
