If any value in the data is negative, then it is impossible to calculate _______?
Correct answer: D. G.M.
- A. A.M.
- B. Mode
- C. H.M.
- D. G.M.
Explanation
The usual real-valued geometric mean is defined for non-negative observations, so a negative value makes it unavailable under the standard definition. Arithmetic mean and mode can still be calculated, while the harmonic mean mainly fails when a value is zero.
