Answer
14

The correct answer is 14 — Compute their average: (12+16) ÷ 2 = 14. This is the median.

Step-by-step solution

  1. Arrange the data in ascending order (already ordered). This is needed to locate the middle values.
  2. Count the number of observations: 6, which is even. For an even set, the median is the average of the two middle values.
  3. Identify the third and fourth values: 12 and 16. These are the middle values.
  4. Compute their average: (12+16) ÷ 2 = 14. This is the median.
Common mistake: Taking only the third value instead of averaging the two middle values

Concept tested: Median of an even set
