Moderate
If the smallest observation in a data is decreased, the average which is not affected is______________?
Correct answer: B. Median
- A. G.M.
- B. Median
- C. Mean
- D. Harmonic mean
Explanation
Reducing the smallest observation keeps it at the lower end of the ordered data, so the middle position and hence the median remain unchanged. Means, including the arithmetic, geometric, and harmonic means, are affected by changing an observation.
