Correct Answer

✅ Option c — Median

All Options:

  • AAM
  • BGM
  • CMedian
  • DMode

Detailed Solution & Explanation

In an open-end classification, the first and/or last class intervals do not have defined outer boundaries. Because of this, the arithmetic mean, geometric mean, and harmonic mean cannot be calculated because they require computing the midpoints of all class intervals. The median, being a positional average, only depends on identifying the class interval containing the middle-most observation, which is unaffected by the undefined boundaries of the extreme classes. Thus, median is the best measure of central tendency for open-end classification. Hence, **Option C** is the correct answer.
