Detailed Solution

We have to find the median of the numbers 4, 4, 5, 7, 6, 7, 7, 12, 3.
We know that when n is odd, then the median is given by,
n+1 2 th term
Rearranging the given numbers in ascending order.
3, 4, 4, 5, 7, 6, 7, 7, 12.
The number of terms in the given data is 9 which is odd.
Calculating the median of the data,
= 9+1 2 th term =5th term =6
Hence, the middle term of the data is the 5th term that is, 6.
Therefore, option 3 is correct.
