The marks of 7 students in a unit test are given below :

9, 10, 7, 6, 9, 3, 5

Median of the data is :

7

Marks given are 9 10 7 6 9 3 5. When these are arranged in ascending order we get their sequence as 3 5 6 7 9 9 10.

Total numbers (n) = 7

Hence their median would be = \(\frac{n + 1}{2}\)th term              [if total numbers are odd terms]

⇒ \(\frac{7 + 1}{2}\)th term = 4^th term,  which is 7.
