Some measures of central tendency for n discrete observations are given below: 1. Arithmetic mean 2. Geometric mean 3. Harmonic mean 4. Median A desirable property of a measure of central tendency is if every observation is multiplied by c then the measure of central tendency is also multiplied by c , where c 0 . Which of the above measures satisfy the property?
