Question

Find the median:

7, 14, 21, 15, 19, 18, 6, 10, 14

Answer 1

Given: 7, 14, 21, 15, 19, 18, 6, 10, 14

Step-wise calculation:

1. Arrange in ascending order: 6, 7, 10, 14, 14, 15, 18, 19, 21.

2. Count the number of observations: n = 9 (odd).

3. For odd n, median is the `((n + 1)/2)`th observation = `(9 + 1)/2` = 5th observation.

3. The 5th observation in the ordered list is 14.

Median = 14.
