When there is 0 in our dataset which mean we cannot calculate?
Correct answer: D. Both A and B
- A. GM
- B. HM
- C. AM
- D. Both A and B
Explanation
A zero makes the geometric mean zero and makes the harmonic mean undefined because it requires reciprocals of the observations. The arithmetic mean can still be calculated, so both GM and HM are affected.
