The median of the given data is:

7, 5, 2, 3, 6, 9, 1

5.5

✅ Correct Option: 2

The given data is:

7, 5, 2, 3, 6, 9, 1

Arrange the numbers in ascending order:

1, 2, 3, 5, 6, 7, 9

Count the total numbers: 7 numbers (odd count)

For an odd count, the median is the middle value.

Middle position $= \dfrac{n + 1}{2}$

$= \dfrac{7 + 1}{2}$

$= 4$

The 4th position in the ordered list:

1, 2, 3, 5, 6, 7, 9

The 4th number is 5.

Therefore, the median is 5.
