Question

Find the median of the following data:

25, 18, 16, 9, 11, 17, 29, 35, 6

Answer 1

Given: 25, 18, 16, 9, 11, 17, 29, 35, 6

Step-wise calculation:

1. Arrange in ascending order:

6, 9, 11, 16, 17, 18, 25, 29, 35

2. Number of observations n = 9 (odd).

3. For odd n, median = `((n + 1)/2)`th term

= `(9 + 1)/2`

= 5th term

4. The 5th term in the ordered list is 17.

Median = 17.
